Right. The letter n stands for the exponent, and this tells us how far to go in multiplying our base by itself.

It is necessary to know how the letters b and n are sometimes tossed around in discussing powers.

If, for example, b = 3, then b^{n} means that 3 is raised to the nth power, or 3 is used as a factor n times.

If n = 4, then b^{n} means that b is raised to the 4th power, or b is used as a factor 4 times.

Now we have defined the 2nd power of a base, b^{2}, and the 3rd power, b^{3}, and so on, but we have not defined the 1st power of a number, have we? Do you know what we mean by the 1st power of any number, b?
