Question

Class 8 Problem
ALGEBRA ​

Answer 1

Answer:

62

Step-by-step explanation:

x + 1/x = 8

square on both sides,

x² + 1/x² + 2(x)(1/x) = 8² = 64

so on solving,

x² + 1/x² = 64-2 = 62

Answer 2

Answer:

x+1/x=8

squaring on both sides

(x+1/x)^2 = 64

x^2 + 1/ x^2 +2× x × 1/x = 64

x^2+1/x^2 +2 =64

x^2 +1/ x^2 = 62
