Cancel the common factors.

Factor $2$ out of $10$ .

$\log (I) + 12 = \frac{2 \cdot 52}{2 \cdot 5}$

Cancel the common factor.

$\log (I) + 12 = \frac{2 \cdot 52}{2 \cdot 5}$

Rewrite the expression.

$\log (I) + 12 = \frac{52}{5}$

Move all terms not containing $\log (I)$ to the right side of the equation.

Subtract $12$ from both sides of the equation.

$\log (I) = \frac{52}{5} - 12$

To write $- 12$ as a fraction with a common denominator, multiply by $\frac{5}{5}$ .

$\log (I) = \frac{52}{5} - 12 \cdot \frac{5}{5}$

Combine $- 12$ and $\frac{5}{5}$ .

$\log (I) = \frac{52}{5} + \frac{- 12 \cdot 5}{5}$

Combine the numerators over the common denominator.

$\log (I) = \frac{52 - 12 \cdot 5}{5}$

Simplify the numerator.

Multiply $- 12$ by $5$ .

$\log (I) = \frac{52 - 60}{5}$

Subtract $60$ from $52$ .

$\log (I) = \frac{- 8}{5}$

Move the negative in front of the fraction.

$\log (I) = - \frac{8}{5}$

Rewrite $\log (I) = - \frac{8}{5}$ in exponential form using the definition of a logarithm. If $x$ and $b$ are positive real numbers and $b \neq 1$ , then $\log_{b} (x) = y$ is equivalent to $b^{y} = x$ .

$10^{- \frac{8}{5}} = I$

Solve for $I$ .

Rewrite the equation as $I = 10^{- \frac{8}{5}}$ .

$I = 10^{- \frac{8}{5}}$
