Question

x= 2-root3 . Find (x-1/x)cube​

Answer 1

Answer

X= 2- root 3

1/x= 2+root 3

x-1/x= - 2 root 3

Cubing both sides

(X-1/x)cube= (2root 3)cube

= 24root 3

Plz mark me as brainliest.

Answer 2

x=2-√(3)........1

1/x=1/2-√3

=1/2-√(3)*2+√(3)/2+√(3)

=2+√(3)/2∧2-√(3)∧2

=2+√(3)/4-3

=2+√(3)........2

(x-1/x)∧3=(2-√(3))+(2+√(3))

=(-3.46)∧3

=-41.421736

=-42

i think this is the answer

hope this will help u
