Solution
- The solution steps are given below:
[tex]\begin{gathered} (\frac{4m^5n^2}{m^2n})^3 \\ \\ =(\frac{4\times m^{2+3}n^{1+1}}{m^2n})^3 \\ \\ =(\frac{4\times m^2n\times m^3n}{m^2n})^3 \\ \\ =(\frac{4\times m^3n}{1})^3 \\ \\ =4^{1\times3}\times m^{3\times3}\times n^{1\times3} \\ \\ =4^3m^9n^3 \\ \\ =64m^9n^3\text{ \lparen OPTION A\rparen} \end{gathered}[/tex]
