Answer:
'Add Them'
Explanation:
Rules for indices:
First law: multiplication
If the two terms have the same base (in this case x) and are to be multiplied together their indices are added.

Second law: Division
If the two terms have the same base (in this case ) and are to be divided their indices are subtracted.

Third law: Brackets
If a term with a power is itself raised to a power then the powers are multiplied together.

Fourth law: Negative Power

Fifth law: Power of Zero

Sixth law: Fractional Power
The top line of the fractional power gives the usual power of the whole term. The bottom of the fraction stands for the type of root.
