Basically for questions like these, you have to make the denominator a whole number with no surds, so you multiply it by the same numbers but change the sign. Whatever you do at the bottom you have to do at the top so

and then you expand

Step-by-step explanation:

3/(√5+√2) = 3/(√5+√2) × (√5-√2)/(√5-√2)
