$straight x space plus space 1 over straight x space equals space 2$ ,
Put the value of x = 1 as it satisfies the equation,
$1 plus 1 over 1 space equals space 2$
$therefore space space space space space straight x to the power of 99 space plus space 1 over straight x to the power of 99 space minus space 2 space equals space left parenthesis 1 right parenthesis to the power of 99 space plus space fraction numerator 1 over denominator left parenthesis 1 right parenthesis to the power of 99 end fraction minus 2 space equals space 2 space space minus space 2 space equals space 0$
