Answer 3

So we want to simplify. For number 1 multiply the two terms together so that you have\[\frac{ 16x^3 • 5y^2 }{ x•y^2}\]

Answer 4

rearrange to group like terms together easier to see what to do
to multiply numbers with the same base add the exponents
to divide numbers with the same base subtract the exponents
