x 1 + x 2 1 + x 3 1 = 3 . 1 4 1 5 9 2 6
If x satisfy the above equation, what is the value of ( x 2 0 1 5 × x 2 0 1 0 ) × ( x − 1 9 4 5 × x − 2 0 8 0 ) ?

plot twist at end
Now that's what I call "hardcore" * thumbs up * (Y).
If only I can upvoted more than once..... I will give you 1 0 0 0 upvote by now! XD
Finally done with other 2 complex roots. Much hard work out there XD
Good to see your solution and now, I know XD
Salute from me too men.
Wow, this should have been too tiring!
I was wondering if that is correct.

Try that by yourself and see what happens! :3
Im...... probable
why spend so much time on the first statement

@Sambhaw Kumar This is a Lvl 1 math question so I will be as detailed as possible. -w-
Why have you choosen so long a method when you can simply solve it by product rule?? a single step ans man..!!

That was a sarcastic hyperbole :P

It won't harm to take just 1-2 extra steps! (´ ω `♡)

You have my respect
2 0 1 5 + 2 0 1 0 − 1 9 4 5 − 2 0 8 0 = 0 Thus, x 0 = 1
The given expression = square root of[x^(2015 + 2010 - 1945 - 2080)] =
square root of[x^0] = 1
2015+2010-1945-2080=0 Therefore, x^0 = 1
irrespective of given condition. ans :-x^(4025-4025)= x^0=1
I'm quite shocked when I see this is level 1
It turns out doesn't have to do with pi
Well, because the first statement is a decoy~ :v

@Nicholas Vincent – wih keren yaa udah solved banyak problem
hey follback yaa :3
4025-4025=0; anything power 0=1; so x power 0 also=1; and sqr root of 1 is 1. so the answer is 1.
x^(2015+2010)=x^4025 ; x^(-1945+-2080)=x^-4025 , multiplying we will get 1 and √1=+-1
When you are taking square root, we get positive real numbers. So the answer is positive one
Rules of exponents. Enough said.
multiply them not more than that

We know that x = 0 in this problem, so we can multiply both sides by x 3 . The equation will become
x 2 + x + 1 = 3 . 1 4 1 5 9 2 6 x 3
3 . 1 4 1 5 9 2 6 x 3 − x 2 − x − 1 = 0

Plugging in the question for every values we get for sure, we get
( x 2 0 1 5 × x 2 0 1 0 ) × ( x − 1 9 4 5 × x − 2 0 8 0 ) = x 2 0 1 5 + 2 0 1 0 − 1 9 4 5 − 2 0 8 0 = x 0 = 1 = 1 ~~~
