Question

Answer 1

Step-by-step explanation:

x equal to 1-root 2 upon 3

Answer 2

Step-by-step explanation:

If, x=1-√2

x-(1/x)³

1-√2-(1/1-√2)³

1-√2-(1/(1-√2)(1+2+√2)

1-√2-(1/(1-√2)(3+√2)

1-√2-(1/(3+√2-3√2-2)

1-√2-(1/1-2√2)

(1-√2)(1-2√2)-1/(1-√2)

1-2√2-√2+4-1/(1-√2)

4-3√2/1-√2(1+√2/1+√2)

(4-3√2)(1+√2)/1-(√2)²

4+4√2-3√2-6/-3

(√2--6/-3)-

6-√2/3.
