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.
3 divided by 5 times the square root of 5 + 3 times the square root of 2. (This problem is written as a fraction.)
