[" 66."(1)/(sqrt((12-sqrt(140))))-(1)/(sqrt((8-sqrt(60))))-(2)/(sqrt(10+sqrt(84)))],[" (a) "0]

The value of (1)/(sqrt(12-sqrt(140)))-(1)/(sqrt(8-sqrt(60)))-(2)/(sqrt(10+sqrt(84)))

(1)/(sqrt(11-2sqrt(30)))-(3)/(sqrt(7-2sqrt(10)))-(4)/(sqrt(8+4sqrt(3)))

Simplify: (1)/(sqrt(11-2sqrt(30)))*(3)/(sqrt(7-2sqrt(10)))(4)/(sqrt(8+4sqrt(3)))

The value of (1)/(sqrt(10) - sqrt(9)) - (1)/(sqrt(11)-sqrt(10)) + (1)/(sqrt(12) - sqrt(11))………. - (1)/(sqrt(121) - sqrt(120)) is equal to
