Answer 1

Answer:

x - 1/x = 6  ;   x^4 + 1/x^4 = 1442

Step-by-step explanation:

x^2 + 1/x^2 = 38

question 1 :

(x - 1/x)^2 = x^2 + 1/x^2 - 2x*1/x

(x - 1/x)^2 = 38 - 2 = 36

x - 1/x = √36 = 6

question 2 :

(x^2 + 1/x^2)^2 = x^4 + 1/x^4 + 2x^2*1/x^2

(38)^2 =  x^4 + 1/x^4 + 2

x^4 + 1/x^4 = 1444 - 2 = 1442
