$\log_{4} (5) + \log_{4} (x) = \log_{4} (60)$

Step 1

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

$\log_{4} (5 x) = \log_{4} (60)$

Step 2

For the equation to be equal, the argument of the logarithms on both sides of the equation must be equal.

$5 x = 60$
