Question

Polynomials please someone help me !!!



(x4)2

Answer 1

I strongly believe you meant (x^4)^2 as you're referring to polynomials.


(x^4)^2

= (x^4)*(x^4)

= (x*x*x*x)*(x*x*x*x)

= x^8

On the other hand, if you meant (x^4)2, then the answer is 2x^4

Hope this helps! :3

Answer 2

remember
(x^n)^m=x^(mn)

(x^4)^2=x^(4*2)=x^8
