Need help quick simplify the expression (-4) power of 3
dezoksy [38]

Answer:

-64

Step-by-step explanation:

The question is asking to solve (-4)^3

Notice how the -4 is in parenthesis. This means that along with the 4 being multiplied, the negative is too.

(-4)^3 is the same as -4 · -4 · -4

First let's figure out if this will be negative or positive

Whenever the exponent is odd and there is a negative in the parenthesis the answer will be negative and if its even it will be positive

Now find out what 4 x 4 x 4 equals (64)

In conclusion the answer is -64
