$\log_a b \Longleftrightarrow \frac {log_c b}{log_c a}$

$\log_9 x = \frac {3}{2}$

$\log_9 x = \frac {logx}{log9}$

$\frac {logx}{log9} = \frac {3}{2}$

Solve for x. Please note that logarithms should be part of the Algebrea/Pre-Algebra category, and not pre-calculus.

$log_a(b)=c \iff a^c=b$
$log_9(x)=\frac{3}{2} \iff 9^{\frac{3}{2}}=x \iff 27=x$
