How do you multuply monominails (sorry if i spelled it wrong)

a^3 * v^4

A^3 * v^4 = (a^3) (v^4) which is your answer

If both terms had the same base (ex. were both a), then we could add the exponents and have a^7

The correct spelling is "monomials"

mono = one

nomial = name

so monomial translates to "one name"

As for the actual question of multiplying monomials, there isn't anything we can do here. The reason why is because the bases 'a' and 'v' are different. If they were both the same letter, then we'd be able to add the exponents. However that is not the case here. So we'd just leave it as a^3*v^4
