8u18w45x4a18

step-by-step explanation:

                  1

simplify   —

                  2

                                                                            1

  ((•(u9))•(w17))•(•((4•(a3))•(•(•a15)•u9))

                                                                            2

equation at the end of step   2   :

                                                                            a15

  ((•(u9))•(w17))•(•((4•(a3))•(•(•u9))

                                                                              2

equation at the end of step   3   :

                                                                          u9a15

  ((•(u9))•(w17))•(•((4•(a3))•(•(

                                                                              2

equation at the end of step   4   :

                                                                  -u9a15

  ((•(u9))•(w17))•(•(22a3•w28))•

                                                                        2    

equation at the end of step   5   :

                                                                  -u9a15

  ((0 -   ((22u9 • w17) • x4)) • 22w28a3) •

                                                                        2  

step   6   :

multiplying exponential expressions :

    u9 multiplied by u9 = u(9 + 9) = u18

multiplying exponential expressions :

    a3 multiplied by a15 = a(3 + 15) = a18

dividing exponents :

    24   divided by   21   = 2(4 - 1) = 23

final result :

  8u18w45x4a18
