Question

Como resolver?

(2/3)³ x (2/4)-² x 3/2 x (3/2)² x 8

Answer 1

              
                     (2/3)³ x (2/4)-² x 3/2 x (3/2)² x 8 =
                      8/27 x (4/2)²  x  3/2 x 9/4  x 8 =
                      8/27 x  2²  x 27 =
                      8/27 x 4 x 27 =  8 x 4 = 32

Explicação:
                     3/2 x 9/4 x 8 =   (simplifica cruzado --> 8 com 4)
                     3/2 x 9 x 2 =      (simplifica cruzado --> 2 com 2)
                       3  x 9      =  27

                      8/27 x 4 x 27 =  (simplifica 27 com 27)
                         8   x 4         = 32
