Answer

$3$ $log$ ${m}$ - $4$ $log$ ${n}$ + $2$ $log$ ${p}$

Work Step by Step

Use the Quotient Property of Logarithms. According to this property, $log_b$ ${m}$ - $log_b$ ${n}$ = $log_b$ $\frac {m}{n}$: $log$ ${m^{3}}$ - $log$ ${n^{4}p^{-2}}$ Use the Product Property of Logarithms. According to this property, $log_b$ ${mn}$ = $log_b$ ${m}$ + $log_b$ ${n}$: $log$ ${m^{3}}$ - ($log$ ${n^{4}}$ + $log$ ${p^{-2}})$ Use the Power Property of Logarithms to rewrite this expression. The property states that $log_b$ ${m^n}$ = $n$ $log_b$ ${m}$: $3$ $log$ ${m}$ - ($4$ $log$ ${n}$ - $2$ $log$ ${p})$ Use distributive property: $3$ $log$ ${m}$ - $4$ $log$ ${n}$ + $2$ $log$ ${p}$
