Step-by-step explanation:

(i)

          >> ( x  +  1/x )^2   equal to  x^2  +  1/x^2  + 2

          >> ( x  +  1/x )^2  -  2 equal to  x^2  +  1/x^2    

          >> (5)^2  -  2 equal to  x^2  +  1/x^2

          >> 23  equal to  x^2  +  1/x^2

(ii)

          Similarly like (i)

 

          >> ( x^2  +  1/x^2 )^2  equal to  x^4  +  1/x^4  + 2

          >>  ( x^2  +  1/x^2 )^2   -  2 equal to  x^4  +  1/x^4

          >>  (23)^2  - 2  equal to  x^4  +  1/x^4

          >>  527   equal to  x^4  +  1/x^4
