Answer 1

HELLO DEAR,


x² + 1/x² = 27

x² + 1/x² - 2*x*1/x + 2*x*1/x = 27

(X - 1/x)² = 27 - 2

(x - 1/x) = 5


I HOPE ITS HELP YOU DEAR,
THANKS

Answer 2

solution:-

given by:-
${x}^{2} + \frac{1}{ {x}^{2} } = 27 \\ {( {x}^{2} + \frac{1}{ {x}^{2} } ) }^{2} = {x}^{4} + \frac{1}{ {x}^{4} } + 2 = 729 \\ {x}^{x} + \frac{1}{ {x}^{4} } = 727 \\ {( {x}^{2} - \frac{1}{ {x}^{2} }) }^{2} = {x}^{4} + \frac{1}{ {x}^{4} } - 2 \\ {(x}^{2} - \frac{1}{ {x}^{2} } ) = \sqrt{727 - 2} \\ = \sqrt{725}$
