1 5
- 5
- 25

Correct Option: C
∴ | = | |||
3x - 2y | 6 |
⇒ 18x – 12y = 10x +15y
⇒ 18x – 10x = 12y + 15y
⇒ 8x = 27y
⇒ | = | |||
y | 8 |
On taking cube root of both sides,
= | = | ||||
³√y | ³√8 | 2 |
By componendo and dividendo,
= | = | ||||
³√x - ³√y | 3 - 2 | 1 |
On squaring both sides,
⇒ | ![]() | ![]() | 2 | = 5 × 5 = 25 | ||
³√x - ³√y |
