35   x   45 6   x   5 = 6   x   6   x   9   x   5 6   x   5 = 6   x   9 = 54

= 54 cậu nhé

 2 x 39 x 5

= 39 x (2 x 5)

= 39 x 10 = 390

2 x 26 x 5

= 26 x (2 x 5)

= 26 x 10 = 260

134 x 4 x 5

= 134 x (4 x 5)

= 134 x 20 = 1680

2 x 134 x 5 = (2 x 5) x 134

                   = 10 x 134

                   = 1340
