Answer 1

\[14\times 5=70\] so ignore answers 1 and 3

Answer 2

if you just multiply them together the first thing you get is
\[\frac{70x^2y^2}{xy^2}\] then you can cancel one \(x\) top and bottom, and both \(y\)'s

Answer 3

Ok so

Answer 4

is it B?

Answer 5

no, you should cancel

Answer 6

\[\frac{70x^2y^2}{xy^2}=\frac{70x^{\cancel{2}}\cancel{y^2}}{\cancel{x}\cancel{y^2}}=70x\]
