Answer 2

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
