_____________________________

Given :-

x² + 1 / x² = 62

To find :-

x + 1 / x

Salutation :-

x² + 1 / x² = 62

( x + 1 / x )² - 2 × x × 1 / x = 62 [ • Using identity ]

( x + 1 / x )² - 2 = 62

( x + 1 / x )² = 62 + 2

( x + 1 / x )² = 64

( x + 1 / x )² = ( 8 )²

( x + 1 / x ) = 8

•°• The value of ( x + 1 / x ) is 8.
