Exercise 71 Page 423

What does the Negative Exponent Property say?

-7.25

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.

2^(-1)-1/3^(-2)+5(1/2^2)

NegExponentToFrac

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

1/2^1-1/1/3^2+5(1/2^2)

a/b/c= a * c/b

1/2^1-1(3^2)/1+5(1/2^2)
