Simplify 1/(sqrt(45) + sqrt(36)) + 1/(sqrt(36) + sqrt(27)) + 1/(sqrt(27) + sqrt(18)) + 1/(sqrt(18) + sqrt(9))

Ill give you some hints:

sqrt(45) = sqrt(9*5) = 3 sqrt(5)

sqrt(36) = 6

sqrt(27) = sqrt(3*3*3) = 3 sqrt(3)

sqrt(18) = sqrt(9*2) = 3 sqrt(2)

sqrt(9) = 3

It should be easy from here, just plug in the simplified version in for the unsimplifiied, and then you will see what to do from there! laugh
