Question

x=2-√3 find the value of (x-1/x)3.

Answer 1

Simply put the value of x in the given equation:

(x-1/x)³= ((2-√3) - 1/(2-√3))³

Take LCM and solve it :

= (((2-√3)(2-√3) - 1)/(2-√3))³ (solve it in your notebook)

= ((6-6√3)/(2-√3))³

= (2(2-√3)/(2-√3))³ ( (2-√3) will cancel out )

= (2)³

= 8
