Logarithm
The exponent to which a base must be raised to get a number.
Definition
A logarithm answers the question: 'To what power must the base be raised, to produce a number x?' It is the inverse of exponentiation.
Example
log2(8) = 3 because 2^3 = 8
Calculation
logbasevalue= exponent
Example:log28 = ?
Since 2³ =8,
log₂ 8 =3
Since 2³ =8,
log₂ 8 =3
