Question

Change the mixed expressions to fractions y+2 y^3/x^3-y^3

Answer 1

The common denominator for each of these terms is x^3 so the new expression would be:

`(x^(3)y)/(x^(3)) + (y^(3))/(x^(3)) - (x^(3)y^(3))/(x^(3))`
so to simplify that down to a single fraction

`(x^3y + y^(3)-x^(3)y^(3))/(x^(3))`
