The Deep Dive
To solve \( \left(\frac{1}{2} m^{2} n^{-2}\right)^{3} \), we apply the power of a product rule. Raise both the fraction and the variables to the power of 3: \[ = \left(\frac{1}{2}\right)^{3} \cdot \left(m^{2}\right)^{3} \cdot \left(n^{-2}\right)^{3} \] Calculating each part: \[ = \frac{1}{8} \cdot m^{6} \cdot n^{-6} \] So, the final answer is: \[ = \frac{m^{6}}{8n^{6}} \]
