What does the Negative Exponent Property say?
4/25
To evaluate 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. We will start by rewriting a decimal as a fraction.
a = 10* a/10
a(- b)=- a * b
Put minus sign in front of fraction
a^(- m)=1/a^m
(- a)^2=a^2
(a/b)^m=a^m/b^m
a/b/c= a * c/b
a * 1=a
Calculate power
a/b=.a /25./.b /25.
