I. ` 7/sqrtx + 5/sqrtx = sqrtx `
II. `y^(2) -((12)^(5//2))/sqrty = 0`

A

` x gt y`

B

` x ge y`

C

`x lt y`

D

x = y or the relationship cannot be established.

Text Solution

Verified by Experts

The correct Answer is:
D
I. ` 7/sqrtx + 5/sqrtx = sqrtx`
` rArr 7+5 = sqrtx xx sqrtx `
` rArr x = 12`
II. ` y^(2) - ((12)^(5//2))/sqrty = 0`
` rArr y^(2+1/2) - (12)^((5//2)) = 0`
` rArr y^(5//2) = 12^(5//2)`
` rArr y = 12`
