Question

Which of the following is equivalent to x^5y^2 / xy^2 when x /= 0 and y /= 0.

Answer 1

x^6y^5
x^5y
x^4y
x^4

Answer 2

Since \(x\not=0\), that means given the rational expression \(\dfrac{x}{x}\), you can simplify it to 1.

So,
\[\frac{x^5y^2}{xy^2}=x^4\]
because you can eliminate the factors of \(y^2\) and one factor of \(x\).

Answer 3

Thanks for the help :)
