Solution :
_________________
i ) √45 = √(3×3×5) = 3√5
ii )√24 = √(2×2×6) = 2√6
____________________
LHS = 2√6 - (√5/√45)-√24
= 2√6-(√5/3√5)-2√6
= -1/3
RHS = a + √30
Compare LHS and RHS , we get
a = 1/3

HEY .....(^_^)
√3 + √2 / √3 - √2
= (√3 + √2 / √3 - √2 ) × ( √3 + √2 / √3 + √2)
= (√3 + √2)^2 / (√3)^2 - (√2)^2
= [ (√3)^2 + (√2)^2 + 2×√3×√2 ] / 3-2
= 3 + 2 + 2√6 / 1
= 5 + 2√6
