how is 2^3^2 = 2^9
Log in to reply
Hi, Hrishikesh!
Firstly, just consider the power of 2 , that is 3 2 . Now we can simplify the power further, 3 2 = 9 . Now, since this is the power of 2 in the given question, we will simply put this as the power of 2 . So we get- 2 ( 3 2 ) = 2 9 = 5 1 2 .
Did you get it, or is there any other doubt?
That's true Akshat it can confuse many . However great explanation !!!
Don't think of 2 3 2 as ( 2 3 ) 2 = 2 6
Instead it is 2 ( 3 2 )
So, firstly evaluate 3 2 which is 9
Now finally evaluate 2 9 which comes to 512
o
From The question , we simplify 2 3 2 to 2 9 = 5 1 2
easy ya ? forget the calculator now :D
Laws of exponents are applied here. first of all we will take the square of the exponent(3) of 2. the exponent of 2 will become 9 which is equal to 512
2^n^m = 512 where: n=3 m=2
n^m = 3^2 = 9 2^9 = 512
first find 3 power 2 which is nothing but 9 then calculate 2 power 9 which leads to the answer
I put 2 to the third power then i squared it and it gave me 512
3E2=9.then use 9 as the exponent of 2. 2E9=512
I pulled 2^3^2 in the calculator and got 512.
what you do is pretend that the the base two is not there and you square the the 3 by 2 then turns out to be 9 then you use the result as the exponent and do 2 to the ninth power
2 and power 3 & 2 first (3 3)=9 then power of 2 is 9 then multiply 2 nine time with 2 2 2 2 2 2 2 2 2*2= 512
(2)^(3^2)= 2 9
2 9 = 2 x 2 x 2... x 2 = 512
2 3 2 = 2 ( 3 2 ) = 2 9 = 5 1 2
3 2 = 9 , and 2 9 = 5 1 2 , which is our answer.
2^(3^2)=512

This problem has the potential to confuse many. Just for those who got trapped, don't get confuse between 2 3 2 and ( 2 3 ) 2 . The latter one opens to 2 3 × 2 , which has a completely different meaning.
What we want is 2 3 2 , which is actually 2 to the power 3 to the power 2 . Hence we would simplify it as-
2 3 2 = 2 9 = 5 1 2 .
Hence the required value is 5 1 2 .
