$\log_a \dfrac{y^5\sqrt{x}}{x^2}$

#### Work Step by Step

Using the properties of logarithms, the given expression, $\dfrac{1}{2}\log_a x+5\log_a y-2\log_a x ,$ simplifies to \begin{array}{l}\require{cancel} \log_a x^{1/2}+\log_a y^5-\log_a x^2 \\\\= \log_a \sqrt{x}+\log_a y^5-\log_a x^2 \\\\= \log_a \dfrac{y^5\sqrt{x}}{x^2} .\end{array}
