Answer:

[tex]-4[/tex]

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:

z = 4i

Step-by-step explanation:

As you may or may not know, i represents [tex]\sqrt{1}[/tex].

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

Hope my answer helped!
