Question

Simplify the expression. Write your answer as a power

(-4)^5 * (-4)^7

Answer 1

`(-4)^(12)`Answer:

Explanation:

using the rule of exponents

`a^(m)` ×
`a^(n)` =
`a^((m+n))` , then

`(-4)^(5)` ×
`(-4)^(7)`

=
`(-4)^((5+7))`

=
`(-4)^(12)`

Answer 2

(-4)^12

Explanation:

Hello!

We can use exponent rules to rewrite the equation.

a^b * a^c = a^(b+c)

Simplify:

• (-4)^5 * (-4)^ 7 = (-4)^(5+7)
• (-4)^12

The value of the equation can be calculated by (-4)^12.
