Exercise 25 Page 364

What does the Zero Exponent Property say? How about the Negative Exponent Property?

1

Practice makes perfect

To simplify the given exponential expression, we will use two Properties of Exponents. The first one is the Zero Exponent Property.

Zero Exponent Property
a^0=1, for every nonzero number a

We will also use the Negative Exponent Property.

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

Let's simplify the given expression using these properties.

9^4* 9^(- 2)/9^2

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

9^(4+(- 2))/9^2

a+(- b)=a-b

9^(4-2)/9^2

Subtract term

9^2/9^2

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

9^(2-2)

Subtract term

9^0

a^0=1
