Answer:
well....we can write it as
______
√(4+√15)
if we don't want double rooting system, we can try to remove one. let us try this
4 + √15 = 4 + √5*√3
= (5+3)/2 + √5*√3
= (5 + 3 + 2√5√3)/2
= ((√5)^2 + (√3)^2 + 2√5√3) / 2
= (√5+√3)^2/2
so,
____
√4+√5 = (√5 + √3)/√2
or after rationalising with √2
= (√10 + √6)/2
