Question

How do you multiply `7m^3(3mn+6)`?

Answer 1

`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!
