Properties

Logarithms are exponents, and therefore log properties are exponent properties. Using these properties makes it possible to simplify logarithmic expressions and solve logarithmic equations.

Any base to the power of 0 equals 1. Inversely, the log of one is always zero.

Negative exponents create reciprocals with positive exponents. Therefore, logs of reciprocals create negative results.
