# Logarithm vs Antilogarithm - What's the difference?

logarithm | antilogarithm |

## In context|mathematics|lang=en terms the difference between logarithm and antilogarithm

is that logarithm is (mathematics) for a number $x$, the power to which a given base number must be raised in order to obtain $x$ written $\log_b x$ for example, $\log_\left\{10\right\} 1000 = 3$ because $10^3 = 1000$ and $\log_2 16 = 4$ because $2^4 = 16$ while antilogarithm is (mathematics) the number of which a given number is the logarithm (to a given base).
