`5 +sqrt5 -sqrt5 =`

(sqrt5 - sqrt3)/(sqrt5 + sqrt3) is equal to :

If x= ( sqrt5- sqrt3)/ ( sqrt5+ sqrt3) and y= ( sqrt5+ sqrt3)/( sqrt5- sqrt3) find the value of x^(2) + y ^(2)

Simplify : (\sqrt 5 - \sqrt 3)/(\sqrt 3 + \sqrt 5) \times (\sqrt 5 - \sqrt 3)/(\sqrt 3 -\sqrt 5)

If x= sqrt5+sqrt3 and y = sqrt5-sqrt3 , then x^4 -y^4

((4 +sqrt5)/(4-sqrt5)) +((4-sqrt5)/(4+sqrt5)) =?

Which of the following is the value of sin 27^0-cos 27^0? (a) -(sqrt(3-sqrt(5)))/2 (b) (sqrt(5-sqrt(5)))/2 (c) -(sqrt(5)-1)/(2sqrt(2)) (d) none of these

Show that (3.5)/(5.10) + (3.5.7)/(5.10.15) + (3.5.7.9)/(5.10.15.20)+ …..oo = (5sqrt5)/(3 sqrt3) - 8/5

(iii) (sqrt 5+ sqrt 3)/(sqrt5-sqrt3)+(sqrt5-sqrt3)/(sqrt5+sqrt3) =?

solve (3sqrt5 +sqrt3)/(sqrt5 -sqrt3)

Set of all values of ' x ' satisfying the inequality |2x^2-4x-7|<[1+1/2((costheta)/(costheta/2sintheta/2))^2],-pi/2lt=theta
