Question

If
(x+ 1/x) = 16 find the value of x power 2+1/x²​

Answer 1

Answer:

If x + 1/x = 5, find the value of x2 + 1/x2

Given :

Step-by-step explanation:

If x + 1/x = 5, find the value of x2 + 1/x2

Given :

( x + 1 /x ) = 5

We need to find x2 + 1 / x2

( x + 1 / x )2 = 25

= x2 + 1 / x2 + 2 (x)(1/x) = 25

= x2 + 1/x2 + 2 = 25

= x2 + 1 / x2 = 25 – 2

= x2 + 1 / x2=23

Hence x2  + 1 / x2 = 23

Answer 2

Answer:

Given :

( x + 1 /x ) = 5

We need to find x2 + 1 / x2

( x + 1 / x )2 = 25

= x2 + 1 / x2 + 2 (x)(1/x) = 25

= x2 + 1/x2 + 2 = 25

= x2 + 1 / x2 = 25 – 2

= x2 + 1 / x2=23

Hence x2 + 1 / x2 = 23
