Hello Friend

Here is your answer below,,

$x = 3 - \frac{2}{2} \\ = > x = 3 - 1 \\ = > x = 2 \\ now \: go \: to \: the \: question \\ (i). \\ x {}^{2} + \frac{1}{x {}^{2} } \\ = >( 2) {}^{2} +( \frac{1}{2} ) {}^{2} \\ = > 4 + \frac{1}{4} \\ = > \frac{16 + 1}{4} \\ = > \frac{17}{4} \: \: \: \: \: answer. \\ (ii). \\ x {}^{3} + \frac{1}{x {}^{3} } \\ = > (2) {}^{3} + ( \frac{1}{2} ) {}^{3} \\ = > 8 + \frac{1}{8} \\ = > \frac{64 + 1}{8} \\ = > \frac{65}{8} \: \: \: \: \: answer$
