$\log (2) + \log (4) - \log (7)$

Step 1

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

$\log (2 \cdot 4) - \log (7)$

Step 2

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

$\log (\frac{2 \cdot 4}{7})$

Step 3

Multiply $2$ by $4$ .

$\log (\frac{8}{7})$

Step 4

The result can be shown in multiple forms.

Exact Form:

$\log (\frac{8}{7})$

Decimal Form:

$0.05799194 \dots$
