btw the x is the algebraic one not times and the 2 and 3 in the numerator are meant to be power numbers

When you divide a number raised to a power by that same number raised to a different power the result is that number raised to the difference of teh two powers:

$<br /> \frac {x^a}{x^b} = x^{(a-b)}<br />$

For example:

$<br /> \frac {z^7}{z^5} = z^{(7-5)} = z^2<br />$

You can apply this principle to the x and y terms in your homework problem. As for the 15 in the numerator and 5 in the denominator - I will assume that you know what 15 divided by 5 is.
