Answer 1

You know exponents are different then coefficients right?

Answer 2

this is what I think you mean:
\[a^3b^2 \cdot 4ab^3\]
but please correct me if you really do mean
\[a3b2 \cdot 4ab3\]

Answer 3

It is!! I keep forgetting it doesn't put them up when I paste

Answer 4

let's look at just the a's for a sec
\[a^3 \cdot a \\ a^3 \cdot a^1\]
