1 answer

Is your problem this:

3 / (5√5 + 3√2)

If so, you need to rationalize the denominator to simplify.

Multiply both top and bottom by (5√5 - 3√2), which is the equivalent of 1, to get rid of the radical in the denominator.

3(5√5 - 3√2) / (5√5 + 3√2)(5√5 - 3√2)

3(5√5 - 3√2) / 107

This is as far as you can go to simplify.

I hope this helps and is what you were asking.
