Answer:

B) x³+3x = p - (1/p)

Step-by-step explanation:

Given,

Using (a–b)^3 = a^3 –b^3 –3 ab(a–b) tick the correct of these when x = p^(1/3) – p^(–1/3)  

Given,

(a – b)^3 = a^3 – b^3 – 3 ab(a – b)

Also, given,

x = p^1/3 – p^(-1/3)

So,

x^3 = (p^1/3)^3 – (p^-1/3)^3 – 3.p^1/3.p^(-1/3)(p^1/3 – p^(-1/3))

Now x^3 = p – p^(-1) – 3 x

So, x^3 + 3 x = p – 1/p
