Question

find the difference (4y/xy)-(2x/xy^3)

Answer 1

u must beging by simplify each expresion

Answer 2

\[\frac{4y}{xy}-\frac{2x}{xy^3}\]
\[=\frac{4y}{xy}\times \frac{y^2}{y^2}-\frac{2x}{xy^3}\]
\[=\frac{4y^3}{xy^3}-\frac{2x}{xy^3}\] now that the denominators are the same, subtract in the numerator
