x3y2

Explanation:

Let's look at the x terms first. We have

x5x2

which would evaluate to x3, because of the property xaxb=xab.

There is no other y terms except in the denominator, so it'll stay there. We have

x3y2

as our final answer.

Hope this helps!

y2x3

Explanation:

So, I think the important thing to talk about here is what y2 means.

y2 can also be rewritten as 1y2 because of the negative exponent. For example, 15 is also 15. This is simply the rule of negative exponents. It's an important one! I'd remember it.

So after knowing this, we can arrive at:
x5x2/y2

Then we cancel terms to achieve
x31/y2

Then just invert and multiply to obtain:
y2x3
