Answer:
Option(C)
Step-by-step explanation:
Given p = x^1/3 + x^-1/3
On cubing both sides, we get
⇒ p³ = (x^1/3 + x^-1/3)³
⇒ p³ = (x^1/3)³ + (x^-1/3)³ + 3x^1/3 * x^-1/3(x^1/3 + x^-1/3)
⇒ p³ = x + x⁻¹ + 3x^(1/3 - 1/3)(p)
⇒ p³ = x + x⁻¹ + 3p
⇒ p³ - 3p = x + x⁻¹
Hope this helps!

Answer:
C
Step-by-step explanation:
On cubing both sides, we get
⇒ p³ = (x^1/3 + x^-1/3)³
⇒ p³ = (x^1/3)³ + (x^-1/3)³ + 3x^1/3 * x^-1/3(x^1/3 + x^-1/3)
⇒ p³ = x + x⁻¹ + 3x^(1/3 - 1/3)(p)
⇒ p³ = x + x⁻¹ + 3p
⇒ p³ - 3p = x + x⁻¹
