What does the Negative Exponent Property say?

3/x^5

Practice makes perfect

To simplify the given exponential expressions, 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.

3x^(- 5)
