Question

How do you simplify `\frac { 2x ^ { 2} y } { 5x } \cdot \frac { 15x y ^ { 2} } { y ^ { 4} }`?

Answer 1

`(6x^2)/y`

Explanation:

We would simplify

1) 5 and 15,
2) x and x
3) `y^3` and `y^4`

`(2x^2cancely)/(cancel5cancel x)*(cancel15^3cancelxcancel(y^2))/(y^cancel4)`

then multiply to have one fraction:

`(6x^2)/y`
