*Logarithms

Let a is an arbitrary positive real number except 0. If ax = y, then logay = x

Conversely, the antilogarithm of x is the number y i.e. y = antilogax.

Here ax = y is called arbitrary exponential function and loga y = x is read is log of y to the base a is equal to x. If a = 10, log is called common & if it is e, then called natural.
