Answer:

D) 4^-2

Step-by-step explanation:

Given: 4^4*4^-7*4

If the base is the same, we can add the powers.

a^m * a^n = a^(m + n)

4^4*4^-7*4 = 4^(4 - 7 + 1)

= 4^(5 - 7)

= 4^-2

Answer: D) 4^-2

Hope this will helpful.

Thank you.

Nookie1986 [14]

The method used is Distributive Property.

<h3>What is Distributive property?</h3>

The Distributive Property is an algebraic property that is used to multiply a single value and two or more values within a set of parenthesis.

Given:

(2x² - 1)(3x+2) = (2x²)(3x) + (2x²)(2) + (-1)(3x)+(-1)(2)

Here the property used is Distributive property.

Because distributive property in this way

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

This is how a is being multiplied by with b and c.
