" (iii) "(1)/(sqrt(5)+sqrt(2))

Rationalisation of the denomintor of (1)/(sqrt(5) + sqrt(2)) gives

Rationalize the denominator (1)/(sqrt(5)+sqrt(2)+1)

Rationalise the denominators of the following (1)/(sqrt(5)+sqrt(2))

If sin theta =-4/5 and theta lies in third quadrant, then the value of cos (theta/2) is ............... A) (1)/(sqrt5) B) -(1)/(sqrt5) C) sqrt((2)/(5)) D) -sqrt((2)/(5))

Evaluate using binomial theorem: (i) (sqrt(2)+1)^(6) +(sqrt(2)-1)^(6) (ii) (sqrt(5)+sqrt(2))^(4)-(sqrt(5)-sqrt(2))^(4)

Evaluate using binomial theorem: (i) (sqrt(2)+1)^(6) +(sqrt(2)-1)^(6) (ii) (sqrt(5)+sqrt(2))^(4)-(sqrt(5)-sqrt(2))^(4)

(1)/(2sqrt(7)+sqrt(5))-(1)/(2sqrt(5)+sqrt(7)) simplify

The point P(1,1) is translated parallel to 2x=y in the first quadrant through a unit distance. The coordinates of the point P in the new position are (1+-2/(sqrt(5)),1+-1/(sqrt(5))) (1+-1/(sqrt(5)),1+-2/(sqrt(5))) (1/(sqrt(5)),2/(sqrt(5))) (4) (2/(sqrt(5)),1/(sqrt(5)))

Show that : (1)/(3-2sqrt(2))- (1)/(2sqrt(2)-sqrt(7)) + (1)/(sqrt(7)-sqrt(6))-(1)/(sqrt(6)-sqrt(5))+(1)/(sqrt(5)-2)=5 .
