If $(x^2+\frac{1}{x^2}) = 23, x > 0 $ What is the value of $(x^3+\frac{1}{x^3})$= ?

140 110 -110  -140

110

If $(x^2+\frac{1}{x^2}) = 23, x > 0 $ $(x^3+\frac{1}{x^3})$= ? If $K^2+\frac{1}{K^2}$ = n  then,  K+ \(\frac{1}{k}\) = \(\sqrt {n + 2}\) x+ \(\frac{1}{x}\) = \(\sqrt {23 + 2}\) = 5 $(x^3+\frac{1}{x^3})$= 53 - 3 × 5 = 110
