$\log ({(\frac{A B}{c^{2}})}^{\frac{1}{3}})$

Expand $\log ({(\frac{A B}{c^{2}})}^{\frac{1}{3}})$ by moving $\frac{1}{3}$ outside the logarithm.

$\frac{1}{3} \log (\frac{A B}{c^{2}})$

Rewrite $\log (\frac{A B}{c^{2}})$ as $\log (A B) - \log (c^{2})$ .

$\frac{1}{3} (\log (A B) - \log (c^{2}))$

Expand $\log (c^{2})$ by moving $2$ outside the logarithm.

$\frac{1}{3} (\log (A B) - (2 \log (c)))$

Multiply $2$ by $- 1$ .

$\frac{1}{3} (\log (A B) - 2 \log (c))$

Rewrite $\log (A B)$ as $\log (A) + \log (B)$ .

$\frac{1}{3} (\log (A) + \log (B) - 2 \log (c))$

Apply the distributive property.

$\frac{1}{3} \log (A) + \frac{1}{3} \log (B) + \frac{1}{3} (- 2 \log (c))$

Simplify.

Combine $\frac{1}{3}$ and $\log (A)$ .

$\frac{\log (A)}{3} + \frac{1}{3} \log (B) + \frac{1}{3} (- 2 \log (c))$

Combine $\frac{1}{3}$ and $\log (B)$ .

$\frac{\log (A)}{3} + \frac{\log (B)}{3} + \frac{1}{3} (- 2 \log (c))$

Multiply $\frac{1}{3} (- 2 \log (c))$ .

Combine $- 2$ and $\frac{1}{3}$ .

$\frac{\log (A)}{3} + \frac{\log (B)}{3} + \frac{- 2}{3} \log (c)$

Combine $\frac{- 2}{3}$ and $\log (c)$ .

$\frac{\log (A)}{3} + \frac{\log (B)}{3} + \frac{- 2 \log (c)}{3}$

Move the negative in front of the fraction.

$\frac{\log (A)}{3} + \frac{\log (B)}{3} - \frac{2 \log (c)}{3}$
