x= 1- root2
1/x = 1/1- root2 * 1+ root2/ 1+ root2
= 1 +root2/ (1)^2 - (root2) ^2
1+ root2 / 1 - 2
1 + root2/ -1
1/x = -(1 +root2)
x-1/x = 1-root2+1+root2
x-1/x =2
(x-1/x)^3 = (2)^3 =8 is the answer
1/x = 1/1- root2 * 1+ root2/ 1+ root2
= 1 +root2/ (1)^2 - (root2) ^2
1+ root2 / 1 - 2
1 + root2/ -1
1/x = -(1 +root2)
x-1/x = 1-root2+1+root2
x-1/x =2
(x-1/x)^3 = (2)^3 =8 is the answer
