A logarithm is fundamentally the inverse operation to exponentiation. This means that if you have an equation of the form

[ b^x = y, ]

then the logarithm tells you what power (x) you need to raise the base (b) to in order to obtain (y). In other words, the logarithm of (y) with base (b) is given by:

[ \log_b y = x. ]
