# Logarithm

^{3}. Here 4 is the base, 3 is the power and 64 is the result.

Simply, we can say that by the use of logarithm, we get the answer of the question that " What exponent do we need for one number to become another number"?

__How many 3s do we multiply to get 81.Solution: We need__

**Example:**3 x 3 x 3 x3 = 81, so if we multiply 3 four times with itself, we get 81. Hence logarithm is 4.
