Rationalise the denominators of the following : (i) (1)/(sqrt(7)) (ii) (1)/(sqrt(7)-sqrt(6)) (iii) (1)/(sqrt(5)+sqrt(2)) (iv) (1)/(sqrt(7)-2)

If sqrt(7) = 2.646 then (1)/(sqrt(7)) =?

Rationalise the denominator of (1)/(sqrt(7)+sqrt(6)-sqrt(13))

The value of (1)/( sqrt(7) - sqrt(6)) - (1)/( sqrt(6) - sqrt(5) ) +(1)/( sqrt(5) -2) - (1)/( sqrt(8) - sqrt(7) ) +(1)/( 3- sqrt(8)) is

If x = sqrt(7)+(1)/(sqrt(7)) , then the value of (128)^(x^(2)) is-
