How to simplify an expression with a negative exponent
svetlana [45]

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}

Hope this helps! Please mark as brainliest, thanks!
