What is the definition of a logarithm?

Back

A logarithm is the exponent to which a base must be raised to produce a given number. It is expressed as log_b(a) = c, which means b^c = a.

What is the relationship between logarithms and exponents?

Back

Logarithms and exponents are inverse operations. If b^c = a, then log_b(a) = c.

What is the change of base formula for logarithms?

Back

The change of base formula states that log_b(a) = log_k(a) / log_k(b) for any positive k.
