Answer 2

Answer:

Step-by-step explanation:

IF x=√3+1/2

Then .

,          x³+1/x³

        (√3+1÷2)³+1/√3+1÷2

  (a+b)³=a³+b³+3ab(a+b)

        (√3)³+1³+3×√3×1(√3+1)+8/(√3)³+1³+3×√3×1(√3+1)

         3√3+1+3√3(√3+1)=8/3√3+1+3√3(√3+1)

        3√3+1+9+3√3+8/3√3+1+9+3√3

       6√3+18/6√3+10

      2(3√3+9/3√3+5)

     3√3+9/3√3+5

Then, Rationalising This

         6√3-9
