Simplify each term.

Tap for more steps...

Step 1.1

Simplify $3 \log_{7} (x)$ by moving $3$ inside the logarithm.

$\log_{7} (x^{3}) + 4 \log_{7} (x - 8)$

Step 1.2

Simplify $4 \log_{7} (x - 8)$ by moving $4$ inside the logarithm.

$\log_{7} (x^{3}) + \log_{7} ({(x - 8)}^{4})$

Step 2

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

$\log_{7} (x^{3} {(x - 8)}^{4})$
