\large{\log_{base}}number = {?}

answer

If \log_{b}x = y, then b^y=x.

First, try to write number, the number we are taking the logarithm of, as a power of base, the base of the logarithm.

number can be expressed as power_string.

number can be expressed as base^answer.

base^answer=number, so \log_{base}number=answer.
