$\log_{6} (90)$

Step 1

Rewrite $\log_{6} (90)$ as $\log_{6} (2 \cdot 3^{2} \cdot 5)$ .

$\log_{6} (2 \cdot 3^{2} \cdot 5)$

Step 2

Rewrite $\log_{6} (2 \cdot 3^{2} \cdot 5)$ as $\log_{6} (2 \cdot 3^{2}) + \log_{6} (5)$ .

$\log_{6} (2 \cdot 3^{2}) + \log_{6} (5)$

Step 3.1

Rewrite $\log_{6} (2 \cdot 3^{2})$ as $\log_{6} (2) + \log_{6} (3^{2})$ .

$\log_{6} (2) + \log_{6} (3^{2}) + \log_{6} (5)$

Step 3.2

Expand $\log_{6} (3^{2})$ by moving $2$ outside the logarithm.

$\log_{6} (2) + 2 \log_{6} (3) + \log_{6} (5)$
