$\frac{1}{3} \cdot \log_{5} (64) = \log_{5} (8) + \log_{5} (p)$

Step 1

Rewrite the equation as $\log_{5} (8) + \log_{5} (p) = \frac{1}{3} \cdot \log_{5} (64)$ .

$\log_{5} (8) + \log_{5} (p) = \frac{1}{3} \cdot \log_{5} (64)$

Step 2

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

$\log_{5} (8 p) = \frac{1}{3} \cdot \log_{5} (64)$
