## Answers ( No )

The answer is x^2y. i just took this quiz and this is 100% the correct answer!

LCD of

4and20

(x^2)y xyWithout any mathematical operations involved, ask yourself how many common variables are in the denominators. x^2 is the same as (x)(x)

so we have

4and20(x)(x)(y) (x)(y)

So what we have in common is one (x) and one (y).

The LCD is xy
