When dealing with really large numbers, it is often easiest to express them as a power. A power has two fundamental pieces: the base and the exponent. The exponent tells us how many times we will have to factor the base. So if you have a base of 3 with the exponent of 5, it's the same thing as 3 times 3 times 3 times 3 times 3. You can see how this is a big number expressed in a compact way as a power.
