You can use the following rule to get rid of negative exponents:

or equivalently:

So you can make the exponent positive, but you must also change the X value to its reciprocal. For example,

Let's apply this rule to your equation, and "convert" all the exponents to positive numbers:

This is the same as:

The first 3 terms cancel out. So we're left just with:

We can further reduce this by grouping x^2 and y^2:

And this is as far as we can go.

I hope this helps!
