Answer:

D. 3m

Step-by-step explanation:

We have been given an expression \frac{3m}{m-6}\times \frac{5m^3-30m^2}{5m^2}. We are asked to simplify our given expression.

First of all, we will factor our expression as:

\frac{3m}{m-6}\times \frac{5m^2(m-6)}{5m^2}

To simplify our given expression, we need to cancel out common factors as shown below:

\frac{3m}{1}\times \frac{5m^2}{5m^2}

\frac{3m}{1}\times 1

3m

Therefore, the simplified form of our given expression would be 3m and option D is the correct choice.
