Exercise 59 Page 422

What does the Negative Exponent Property say?

8c^5d^(-4)e^2/11

Practice makes perfect

To simplify the given exponential expression, we will use the Negative Exponent Property. a^(- n)=1/a^n, for every nonzero numbera and integern Let's try to simplify the given expression using this property.

8c^5/11d^4e^(-2)

Write as a product of fractions

8c^5/11 * 1/d^4 * 1/e^(-2)
