The result of raising a number (the base) to a power (the exponent) is the same
number that would be obtained by multiplying the base number together the
number of times that is equal to the exponent.
Example: 34 = 81 is equivalent to 3*3*3*3 = 81.
In this example, the base is 3 and the exponent is 4.
Exponents are written as a superscript number (e.g. 34) or preceded
by the caret (^) symbol (e.g. 3^4).
