Question

How do you simplify
(-4x^2/xz^2)^3?
The options are
A. -64x^2/z^6
B. 64x^3/z^6
C.-64/x^3 z^6
D. -64x^3/z^6

I think the answer is B

Answer 1

Take each and every one of those things inside the parenthesis to the 3rd power...all of it, one at a time.

Answer 2

Right off you will see that B is incorrect because -4^3 is a negative number, not a positive one.

Answer 3

And when you take an exponent to another power, like\[(x ^{2})^{3}\]You mulitply the exponents to get x^6. Does that help you?

Answer 4

Yes it does thank you!
