Which expression is equivalent to (3m)(4m)^2?

Hello there!

Let's follow order of operations to get to our answer.
(3m)(4m)²
Exponents first because these parentheses don't command us to do any operations.
3m(4²m²)
3m(16m²)
48m³
Remember, when multiplying the terms, ADD the exponents!

I really hope this helps!
Best wishes :)
