# How do you evaluate log_16(1/4)?
Mar 23, 2016
$x = - \frac{1}{2}$
#### Explanation:
Let ${\log}_{16} \left(\frac{1}{4}\right) = x$, then ${16}^{x} = \frac{1}{4}$ or
${\left({2}^{4}\right)}^{x} = \frac{1}{{2}^{2}}$ or
${2}^{4 x} = {2}^{- 2}$
Hence $4 x = - 2$ i.e. $x = - \frac{2}{4} = - \frac{1}{2}$
