Answer:

#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!
