$\log_{4} (W) - \log_{4} (x^{\frac{1}{2}} y^{\frac{5}{2}}) + \log_{4} (z^{2})$

Step 2

Use the quotient property of logarithms, $\log_{b} (x) - \log_{b} (y) = \log_{b} (\frac{x}{y})$ .

$\log_{4} (\frac{W}{x^{\frac{1}{2}} y^{\frac{5}{2}}}) + \log_{4} (z^{2})$

Step 3

Use the product property of logarithms, $\log_{b} (x) + \log_{b} (y) = \log_{b} (x y)$ .

$\log_{4} (\frac{W}{x^{\frac{1}{2}} y^{\frac{5}{2}}} z^{2})$

Step 4
