thats right.. 1 and the 3000 0s!
may you explain please why need to add one (1)...??
Log in to reply
because its 1000 so there is the one(1) on the left
For counting the zero we need to add 1
We add 1 bcoz there is one additional number 1 other than 0
just do it
"Just do it" daw ano wala ka pala e
I believe all the other replied are wrong. We had 10 to the 3000 which means we still had one more 0 on that 10 so the 3000 of the power plus the 1 zero from the 10
s, again 1000 log 1000= 3000 +1= 3001 good questions
I dunno man I count 8 didgits yall stooped af
How is it possible that
1=2?
Please tell me the solution im waiting

a=b a^2=ab a^2-b^2=ab-b^2 (a-b)(a+b)=b(a-b) a+b=b 2=1
log(1000^1000) = 1000log1000 = 1000×3 then the final answer be 3000

ya they got me too...it did not say how many zero's ...it said how many digits. so you have a one and then the 3000 other digits.
Yes there are 3000 zeros but you forgot to count 1 as a digit so 3000 zeros + the digit 1 = 3001
how it's not clear
the same thing here!
great but still confused what happens with the ten
10^3 = 1000, which has 4 digits (1+ the value of the power). Similarly 10^6 = 1,000,000, which has 7 digits -- again 1+the value of the power.
So by extension, 1000^1000=(10^3)^1000. To evaluate this, multiply the "powers" together, as Connor has done, to get 10^3000, which by analogy with the above little examples, will have 3000+1 digits, = 3001 digits
Why add the 1?
1000^1000=10^3(1000) =10^3000
10^2=100 --> 3 digits (2+1) 10^3=1000 --> 4 digits (3+1) Likewise
10^3000 --> 3001 digits (3000 + 1) so the answer is 3001
Brilliant idea!!
O thanks... For the help
This is according to the binomial theorem.

10^x is not a binomial, it's a monomial binomial theorem would be more like (a+b)^x would have x+1 terms
1000^1000=10^3000 and answer is 3001 becuase 10^x has x+1 digits 10²=100
fantastic logic.
1 0 0 0 1 0 0 0 = 1 ∗ 1 0 3 0 0 0 = 1 0 3 0 0 0 . This means there are 3,000 zeroes in the answer, however the part where it tricks you comes in when you need to realize that there is also a 1 at the beginning of the answer, therefore we get 3 0 0 0 + 1 = 3 0 0 1 digits.
thanks robert sir,for your nice explanation....
Excellent one! =)
I THINK THE ANS IS INFINITY.......😁
wait so where did he get the 3 from?
That is really useful.
The best (idiots) guide
Duran gave the best answer
simple $ sweet solution
Guyz its just a pattern... we can make a formula to get the no. of digits in the solutions. It goes like this... the formula is x(n)+1 ... where "x" is the no. of zeroes in the base (limited to only 10,100,1000, etc of this type) and "n" is the exponent of the given number. this would give the total number of digits. Here, no. of zeroes=3 and exponent=1000, therefore, 3(1000)+1=3001 ... this is the answer...
Each time you multiply by 1000 you add 3 zeros, so you multiply 1000 times by 1000, then this is 3000 zeros, plus the number one in the beginning. This is 3000+1=3001
Hello, 1 0 0 0 1 0 0 0 can be expressed as ( 1 0 3 ) 1 0 0 0 = 1 0 3 0 0 0 . This number will look like this: 1 0 0 0 0 0 ⋯ 0 0 0 where there are exactly 3 0 0 0 zeroes. Thus, there are 3 0 0 1 digits (including the 1 in front).
Excellent .... & Easy way of explanation...Any person can understand easily.

I must this is the best way to explain the presence of 3000 zero but ironically people are still missing the really easier concept of adding a 1 to the left of these 0s to make it a number and raising the number of total 'digits' to 3001.
Simplified and concise explanation. Thanks for this!
You can simply use log in this types of problem to count digits of big exponents. Just calculate the 10 based logarithm for any other exponent like log(5^56) for calculating the digits of the number 5^56. For knowing details you can visit This Algorithm . But , in this case this algorithm is not effective because it is too big exponent to calculate.
Let 1000^1000=x, taking log both side yhen finding x=10^3000. We have the solution as 10^a has always number of digits a+1 hence 3000+1=3001
An efficient way to find the amount of digits D in an exponent is to use the formula D = floor(1 + (b)Log10(a)), which yields the result of 3001
This is the right way, forgotten by computer generation.
1000^1=1000, 3zeroes,4digits
1000^2=1000000. 6zeroes,7 digits
1000^3=1000000000, 9zeroes,10 digits.
so,1000^1000 has=(3x1000+1)digits=3001 digits
Every time you multiply something by 1000, you add three zeroes. We're already at four from 1000^1, so for the other 999 thousands you add three more. 3x999 + 4 gives you 3001
I am a big fan of simple solution to hairy looking problems .....so here goes 10^2 = 100 : 3 digits ( 2 zeros and 1) 100^2= 10000: 5 digits ( 4 zeros and 1) So you just have to calculate the number of zeros and increase it by one Number of zeros as can be seen by above examples = the numerical product of the power and the number of zeros in the base number So in 1000^1000 , number of zeros = 1000 x 3 ( no of zeros in the base number i.e. 1000) = 3000 and now add one to accommodate 1 So 3001 ....hope I have painted a picture
Did it the same way! Thumbs up! :)
1000^1000=(10^3)^1000=10^3000. now 10^1 =2 digit 10^2=3 digit 10^3=4 digit 10^4= 5 digit that means 10^n contains (n+1) digits. so ,1000^1000 (=10^3000) will contain (3000+1=3001) digits
1 0 0 0 1 has (1+3) digits. 1 0 0 0 2 has (1+3*2) digits. So 1 0 0 0 1 0 0 0 has 1 + 3 ∗ 1 0 0 0 = 3 0 0 1 digits.
go to https://www.quora.com/How-many-digits-are-in-1000-1000
1000 have 4 digits, 1000^2 have 7, ..10, 13,... Number of digits of 1000^1000: 4 + 999*3 equal to 3001 digits
What I did: It's (10^3)^(10^3) So that's 10^(3+3+3+3+3+... 10^3 times ) Therefore: 10^3000. Which is 3000+1 = 3001 digits. Since 10^x has x+1 digits.
No of terms in an exponential expression = ( l o g x ) + 1 , where x is the exponential expression
So, here x = 1 0 0 0 1 0 0 0
No of terms = l o g ( 1 0 0 0 1 0 0 0 ) + 1 = [ 1 0 0 0 ∗ l o g ( 1 0 0 0 ) ] + 1 = [ 1 0 0 0 ∗ l o g ( 1 0 3 ) ] + 1 = [ 1 0 0 0 ∗ 3 ∗ l o g ( 1 0 ) ] + 1 = [ 1 0 0 0 ∗ 3 ∗ 1 ] + 1 = 3 0 0 0 + 1 = 3 0 0 0 1 terms
Do it with logic it will be easy
See, 1000^1=1000 so if power is 1 there are 3 zeros similarly if power is 2 then zeros are 6
applying unitary method u get that if power is 1000 no of zeros is 3000 and there os a 1 in 1000 so no. Of digits is 3000+1
10^1=10 so 1+1 THAT IS ONE IS THE NO. OF ZEROES THAT IS THE POWER AND REST 1 SO 1+1 SIMILARLY 1000^1000=(10^3)^1000 SO 3000 ZEROES AND 1 ONE SO 3000+1=30001
Not the best solution but how i figured it out: 1000 = 4 digits 1000000 = 7 digits 1000000000 = 10 digits
you form a pattern starting at 4 then you add 3 digits for every subsequent power therefore 1000^1000 would be 4+3(999) = 3000-3+4 = 3001
(000+000....1000) times means 3*1000+1=3001
10^1 has 2 digits, 10^3 has 4. 10^4 has 5,..., 10^x has (x+1) digits. 1000^1000 = 10^3(1000) = 10^3000. Therefore 1000^1000 has 3001 digits.
Simple solution
(1000) 1 = 1000 contains 3 zeros
(1000) 2 = 1000000 contains 6 zeros
So (1000) 1 0 0 contains 300 zeros
And (1000) 1 0 0 0 contains 3000 zeros and so total digits are 3001.
For each time you times it by 1000 you are adding 3 digits. You are adding 3 digits 1000 times therefore 3*1000=3000 plus the 1 at the start 30001
There are 3 zeroes in the no. So simply multiply 3 with power of the no. i.e., 1000 Now 3×1000= 3000 so, 3000+ (1)= 3001 1 came from the first digit which is "1"

For positive integer x , any expression 1 0 x ,simplified, has x + 1 digits, e.g. 1 0 0 = 1 , 1 0 1 = 1 0 . Hence, 1 0 0 0 1 0 0 0 = ( 1 0 3 ) 1 0 0 0 = 1 0 3 0 0 0 , so the simplified expression has 3 0 0 0 + 1 = 3 0 0 1 digits.
