Exercise 5 Page 406

Use the Power of a Power Property.

5^8

Practice makes perfect

We are given a numeric expression and want to write an equivalent expression. (5^4)^2 Notice that this expression is the power of a power. Therefore, we can use the Power of a Power Property. This property states that when we have an exponential expression raised to another exponent, we can multiply the exponents.

(5^4)^2

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

5^(4* 2)

Multiply

5^8

Please note we have only shown one of many possible equivalent expressions.
