Question

if x = 1-√2, find the valve of (x-1/x)³​

Answer 1

Answer: 8 is the correct ans.PLEASE MARK ME BRAINLIEST

Answer 2

Answer:

5/2-7√2/4

Step-by-step explanation:

= (1-√2-[-1/√2])^3

=(1-√2+1/√2)^3

rationalize the denominator = (1-√2+√2/2)^3

Calculate the Sum = (1-√2/2)^3

Using: (a-b)^3

=1-3√2/2+6/4-2√2/8

Reduce the fraction with 2 = 1-3√2/2+6/4-2√2/4

Calculate the Sum = 5/2- 3√2/2-√2/4

= 5/2-7√2/4
