Exercise 9 Page 363

Use the Product of Powers Property.

( - 2/5)^5

Practice makes perfect

We are given a numeric expression, and want to simplify it. ( - 2/5)^3 * ( - 2/5)^2 Notice that this expression is the product of two powers with the same base. Therefore, we can start by using the Product of Powers Property. This property states that when multiplying two exponential expressions with the same base, we add the exponents.

( - 2/5)^3 * ( - 2/5)^2

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

( - 2/5)^(3+2)

Add terms

( - 2/5)^5
