Question

1). If x + 1/x = - 4, then find the value of
x^2 + 1/x^2.

2). If x + 1/x = 6, then find the value of
x^4 + 1/x^4

ASAP​

Answer 1

1 ). Squaring both sides,

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

x^2 + 1/x^2 + 2 = 16

x^2 + 1/x^2 = 16 - 2 = 14

Answer = 14

2 ). Squaring both sides,

( x + 1/x) ^2 = 6^2

x^2 + 1/x^2 + 2 = 36

x^2 + 1 /x^2 = 36 - 2 = 34

Again squaring both sides,

( x^2 + 1/x^2)^2 = 34^2

x^4 + 1/x^4 + 2 = 1156

x^4 + 1/x^4 = 1156 - 2 = 1154

Answer : 1154
