Exercise 5 Page 48

Practice makes perfect

To simplify the given exponential expression, we will use the Negative Exponent Property.

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

Let's simplify the given expression using this property.

7^(- 6)

NegExponentToFrac

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

1/7^6

To simplify the given exponential expression, we will once again use the Negative Exponent Property. Let's do this!

1/10^(- 3)

NegExponentToFrac

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

10^3/1

a/1=a

10^3
