Answer
The logarithm (base a) of a chosen number
is the exponent to which the base a must be raised
to obtain the chosen number
Work Step by Step
Using symols, for $a>0, a\neq 1$, and $x>0$,
$y=\log_{a}x$ means $a^{y}=x$.
In words,
y, the logarithm (base a) of a chosen number (x)
is the exponent to which the base a must be raised ($a^y$)
to obtain the chosen number (x)
