Question

Z3=-64 help please I will give brainliest

Answer 1

Answer:

$-4$

Step-by-step explanation:

An exponent is multiplying a number by itself as many times as the exponent says so.

So we need to find a number that times itself 3 times.

-4 fits this.

-4 x -4 x -4

==> -64

z = -4

Answer 2

Answer:

z = 4i

Step-by-step explanation:

As you may or may not know, i represents $\sqrt{1}$.

Since your question is $\sqrt{-64}$, the answer cannot be -4, so i is there to represent it.

Hope my answer helped!
