What does a raised to the power of b mean?
In this case, a and b are numbers, but we have not been told which numbers they are. Sometimes it is useful to talk about numbers in general. Raising a to the power of b means that the number a gets multiplied by itself, a number of times that is specified by b. So for example, if a is 3 and b is 5, then 3 to the fifth power is 3 x 3 x 3 x 3 x 3. If we do the multiplications, we would wind up with 243.
