21m^4n + 42m^3

This is how I multiplied it:

Explanation:

7m^3(3mn+6)

You solve this by distributing. That means that you "distribute" or multiply the 7m^3 to everything inside the parenthesis, like this:
7m^3 * 3mn = 21m^4n

7m^3 * 6 = 42m^3

Now we add these two together to get the answer:
21m^4n + 42m^3

Hope this helps!
