Question

if x = √2+1, find the value of x² + 1/x²​

Answer 1

Answer:

Step-by-step explanation:

Value of  is 6.

Step-by-step explanation:

Given:

To find:

x² = ( 1 + √2 )² = 1² + (√2)² + 2 × 1 × √2 = 1 + 2 + 2√2 = 3 + 2√2

                       

Now,

Therefore, Value of  is 6Value of  is 6.

Step-by-step explanation:

Given:

To find:

x² = ( 1 + √2 )² = 1² + (√2)² + 2 × 1 × √2 = 1 + 2 + 2√2 = 3 + 2√2

                       

Now,

Therefore, Value of  is 6

Answer 2

(√2+1)^2 + 1/(√2+1)^2

2+1 + 1/2+1

3+ 1/3

10/3
