Question

solve it plzzzz if any one

Answer 1

$x = 3 + \sqrt{3} \\ \\ {x}^{2} + \frac{9}{ {x}^{2} } = ( {3 + \sqrt{3} })^{2} + \frac{9}{(3 + \sqrt{3}) ^{2} }$
$(3^{1} + {3}^{ \frac{1}{2} })^{2} + \frac{9}{(3^{1} + {3}^{ \frac{1}{2} })^{2}} \\ \\ ( {3}^{1 + \frac{1}{2} } )^{2} + \frac{9}{( {3}^{1 + \frac{1}{2} } )^{2}} \\ \\ ({3}^{ \frac{3}{2}}) ^{2} + \frac{9}{ ({3}^{ \frac{3}{2}}) ^{2}} \\ \\ {3}^{ \frac{3}{2} \times 2 } \times \frac{9}{{3}^{ \frac{3}{2} \times 2 }} \\ \\ {3}^{3} + \frac{9}{ {3}^{3} } \\ \\ 27 + \frac{9}{27} = \frac{729 + 9}{27} = \frac{738}{27} = 27.33$
