To evaluate the expression $\sqrt[3]{64m^3}$, follow these steps:

1. Factor the expression inside the cube root: $64m^3 = 64 \times m^3$

2. Calculate the cube root of each factor separately:

   • $\sqrt[3]{64}$: The cube root of 64 is 4 because $4^3 = 4 \times 4 \times 4 = 64$.
   • $\sqrt[3]{m^3}$: The cube root of $m^3$ is $m$ because $(m)^3 = m^3$.

3. Combine the results: $\sqrt[3]{64m^3} = 4m$

Thus, the evaluated expression is $\boxed{4m}$.
