Answer» 2root(6) - root(5)/3root(5) - 2root(6) = (2root(6) - root(5))(3root(5) + 2root(6))/(3root(5) - 2root(6))(3root(5) + 2root(6)) = (6root(30) + 46 - 35 - 2root(30))/(95 - 46) = (9 + 4root(30))/(45 - 24) = 9/21 + 4root(30)/21 = 3/7 + 4root(30)/21 On comparing with a + broot(30) a = 3/7, b = 4/21

Answer»

2root(6) - root(5)/3root(5) - 2root(6)

= (2root(6) - root(5))(3root(5) + 2root(6))/(3root(5) - 2root(6))(3root(5) + 2root(6))

= (6root(30) + 4*6 - 3*5 - 2root(30))/(9*5 - 4*6)

= (9 + 4root(30))/(45 - 24)

= 9/21 + 4root(30)/21

= 3/7 + 4root(30)/21

On comparing with a + broot(30)

a = 3/7, b = 4/21
