Use logarithms to evaluate 3/(86.37 x 6.285).

Step 1: Set up the logarithmic expression.
Let $X = \sqrt[3]{\frac{38.32 \times 12.964}{86.37 \times 6.285}}$.
Taking the logarithm of both sides:

$$\log X = \log \left( \left( \frac{38.32 \times 12.964}{86.37 \times 6.285} \right)^{\frac{1}{3}} \right)$$

Using logarithm properties $\log(a^b) = b \log a$ and $\log(\frac{a}{b}) = \log a - \log b$:
