Answer:
Flip the fraction that you are applying the exponent to, if it's a whole number, just imagine it's over one and flip it that way.
Explanation:
If you have 3/5 ^-3
You would flip the fraction to 5/3, then the exponent turns to positive 3
So 5/3 ^3
For a whole number, for example, 6, ^-2
In other words, it's 6/1 ^2, so you would make it 1/6, then the exponent turns positive.
So 1/6 ^2
