Option 1: ${p}^2+1$
Option 2: ${p}^2+3$
Option 3: ${p}^2-1$
Option 4: $p^2-3$
Correct Answer: $p^2-3$
Solution : Given: $(x^3+\frac{1}{x^3}-k)^2+(x+\frac{1}{x}-p)^2=0$ If the sum of the squares of two numbers is zero then both the numbers will also be zero. ⇒ $(x^3+\frac{1}{x^3}-k)^2=0$ and $(x+\frac{1}{x}-p)^2=0$ ⇒ $(x^3+\frac{1}{x^3}-k)^2=0$ ⇒ $x^3+\frac{1}{x^3} = k$ ----------(i) Also, $(x+\frac{1}{x}-p)^2=0$ ⇒ $x+\frac{1}{x}=p$ ------------(ii) Now, $(x+\frac{1}{x})^3 = x^3+\frac{1}{x^3} + 3(x+\frac{1}{x})$ ⇒ $p^3
