$\log_b x+2\log_b y-\log_b w-3\log_b z$

Work Step by Step

Using the properties of logarithms, the given expression, $ \log_b \dfrac{xy^2}{wz^3} ,$ is equivalent to \begin{array}{l}\require{cancel} \log_b (xy^2)-\log_b (wz^3) \\\\= \log_b x+\log_b y^2-\left( \log_b w+\log_b z^3 \right) \\\\= \log_b x+\log_b y^2-\log_b w-\log_b z^3 \\\\= \log_b x+2\log_b y-\log_b w-3\log_b z .\end{array}
