≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
<u>Example:</u>
If the given exponent is a⁻ᵇ, then the result will be 1/aᵇ.
This exponent includes a <u>negative sign.</u> To make the exponent <u>positive</u>, take the exponent's <u>reciprocal</u> and change the <u>negative sign</u> to a <u>positive sign.</u> The same will be done to the given expression.
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
First, take the exponent's reciprocal as said above.

Now, change the exponent's sign.
⇒
⇒
Now, simplify the term.

A)------------------------------------------------------------------------------------------------------
Keep in mind that the exponent is the number of times the base needs to multiply itself.
<u>NOTE:</u> If there are even number of "-", then the result should be positive. If there are odd number of "-", then the result should be negative.
