Logarithmic functions are the inverses of exponential functions, and any exponential function can be expressed in logarithmic form.

What is the relationship between exponentials and logarithms?

Logarithms are the "opposite" of exponentials, just as subtraction is the opposite of addition and division is the opposite of multiplication. Logs "undo" exponentials. Technically speaking, logs are the inverses of exponentials. On the left-hand side above is the exponential statement "y = b^x".

Does logarithm mean exponent?

A logarithm is an exponent. A logarithm is an exponent which indicates to what power a base must be raised to produce a given number. This means the logarithm of 8 to the base 2. It is the exponent to which 2 must be raised to get 8.
