$\log (\frac{\frac{0.94}{0.67}}{5}) = \log (a)$

Step 1

For logarithmic equations, $\log_{b} (x) = y$ is equivalent to $b^{y} = x$ such that $x > 0$ , $b > 0$ , and $b \neq 1$ . In this case, $b = 10$ , $x = \frac{\frac{0.94}{0.67}}{5}$ , and $y = \log (a)$ .

$b = 10$

$x = \frac{\frac{0.94}{0.67}}{5}$

$y = \log (a)$

Step 2

Substitute the values of $b$ , $x$ , and $y$ into the equation $b^{y} = x$ .

$10^{\log (a)} = \frac{\frac{0.94}{0.67}}{5}$
