Question

How to simplify an expression with a negative exponent

Answer 1

Answer:

Step-by-step explanation:

An negative exponent seems hard, but it really isn't!

Let's say you have $2^{-3}$

All you do is inverse the expression, or find the reciprocal. When you do this the exponent changes to positive .  

$\frac{1}{2^{3} }$

$2^{3}$ simplifies into 8. So, the result is

$\frac{1}{8}$
