A logarithm, positive or negative, corresponds to every positive number.

The antilogarithm is the number for which a given logarithm stands. For example, if log x equals y, then x is the antilogarithm of y.

To find the antilog of a number in a given base, raise the base to the number result.

If the logarithm is known, a calculator can be used to find the antilog by pressing the 10x key. This is usually the second function of the log key.

log x = 2.4572

x = 102.4572 = 286.55

Cologarithm

The cologarithm of a number is the logarithm of its inverse, that is to say, the cologarithm of a number is the opposite of its logarithm.

colog 200 = -log 200 = -2.3010

Examples

Using logarithms, calcaute the value of x.
