Answer-I. x= √(20+ √(20+ √(20+ √(20…………….∞)) ) ) II. y= √(5√(5√(5√(5……….∞)) ) )

I. x 20 20 20 20. x 20x By squaring both sides, x220x x2- x-200 x2- 5x4x-200 xx-54x-5 0 x 5,-4 II. y 5555. y 5y By squaring both sides, y25y y5 Hence, xy

Question

I. x= √(20+ √(20+ √(20+

√(20…………….∞)) ) ) II. y= √(5√(5√(5√(5……….∞)) ) ) In each of these questions, two equations numbered I and II are given. You have to solve both the equation and mark the appropriate option – give answer

A If, x>y

B If, x≥y

C If, x

D If, x≤y

E If, x=y or relationship between x and y cannot be established.
