Answer:

Step-by-step explanation:

x=  √3 +√2

1/x = √3 - √2

x³ - 1/x³ =( x - 1/x) + 3(x - 1/x)

            =√3 + √2 - (√3 - √2)   +   3(√3 + √2 - (√3 - √2)

            =√3 + √2 - √3 + √2     + 3 (√3 +√2 -√3 +√2)

            =1(2√2) + 3( 2√2)

             = 1+3(2√2)

              =4(2√2)

              = 8√2
