Answer
$\log A + 2\log B + 3\log C$
Work Step by Step
$Expand$ $the$ $logarithmic$ $expression:$
$\log (AB^2C^3)$
Use the First Law of Logarithms
$\log(A\times B^2\times C^3) = \log A + \log B^2 + \log C^3$
Use the Third Law of Logarithms for $\log B^2$ and $\log C^3$
$$\log B^2 = 2\log B$$
$$\log C^3 = 3\log C$$
$$\log A + 2\log B + 3\log C$$
