How do you add indices?

When working with indices it is important to give examples. When the question is a times, you add the indices, and when it is a divide, you take the indices away. 

For example:

3(2) X 8(3) = 24(5)

You times 3 and the 8 together as normal, and then add the indices. 

8(6) / 4(2) = 2(4)

you divide 4 into 8 as normal, and then take the indices away because it is a divide question, eg. 6-2
