Answer: 18


Step-by-step explanation:x^2+1/x^2= (x+1/x)^2

                                            (x+1/x)^2 = x^2 + 2(x)(1/x) + 1/x^2

                                                            = x^2 + 2 + 1/x^2

                                                            =7+2

                                           (x+1/x)^2 = 9

                                           (x+1/x) = 3

(x^3+1/x^3) = (x+1/x)(x^2 - 1 + 1/x^2)

                   = (3)(7-1)

                   = 3 x 6

                  = 18
