3.1 Logarithmic Form

Logarithms:: If N and a (not equal to 1) are any two positive real numbers and for some real x. ax = N. Then x is said to be the logarithm N to the base a. It is written as loga N = x. This is said to be logarithmic form.

Example:
1. ax = N, write this equation if logarithmic form.
x = loga N.

1. 42 = 16, write this equation if logarithmic form.
2 = log4 16.
