Step 1.1

Simplify $- 2 \log (4)$ by moving $2$ inside the logarithm.

$\log (80) - \log (4^{2})$

Step 1.2

Raise $4$ to the power of $2$ .

$\log (80) - \log (16)$

Step 2

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

$\log (\frac{80}{16})$

Step 3

Divide $80$ by $16$ .

$\log (5)$
