Exercise 13 Page 339

What does the definition of a negative exponent say?

10/t^5

Practice makes perfect

To simplify the given exponential expression, we will use the definition of a negative exponent.

Negative Exponents
a^(- n)=1/a^n, for every nonzero number a

Let's simplify the given expression using this definition.

10t^(- 5)

NegExponentToFrac

a^(- m)=1/a^m

10* 1/t^5
