Direction: In the following questions, two equations numbered I and II are given. You have to solve both questions and give answer
( 1 ) if x > y
( 2 ) if x ≥ y
( 3 ) if x < y
( 4 ) if x ≤ y
( 5 ) if x = y or the relationship cannot be established.
-
Ⅰ. 9 + 19 = √x √x √x Ⅱ. y5 - ( 2 × 14 )11/2 = 0 √y
-
- 1
- 2
- 3
- 4
- 5
Correct Option: E
As per the given above question , we have
| Ⅰ. | + | = √x | ||
⇒ 9 + 19 = √x × √x ⇒ x = 28
| Ⅱ. y5 - | = 0 | |
⇒ y5 √y - ( 2 × 14 )11/2 = 0
⇒ y5 + ( 1/2 ) = ( 2 × 14 )11/2
⇒ y11/2 = ( 2 × 14 )11/2
⇒ y = 2 × 14 = 28
∴ x = y
From above it is clear that x = y is required answer .
