I. ` (18)/x^(2) + 6/x - (12)/x^(2) = 8/x^(2) `
II. ` y^(3) + 9.68 + 5.64 = 16.95`

A

if`x gt y`

B

if `x ge y`

C

if `x lt y`

D

if `x le y`

Text Solution

Verified by Experts

The correct Answer is:
C
`(18)/x^(2) + 6/x - (12)/x^(2) = 8/x^(2)`
` rArr (18+6x-12)/x^(2) = 8/x^(2) rArr 6x + 6 = 8`
` :. X = 2/6 = 0.33`
` II. Y^(3) + 9.68 + 5.64 = 16. 95`
` rArr y^(3) = 16.95 - 15.32`
` rArr y^(3) = 1.63 = y = root(3)(1.63)`
