Exercitiul 10:
6 x 3 + 6 x 12 = 6 x ( 3 + 12) = 6 x 15 = 90
8 x 2 + 8 x 18 = 8 x ( 2 + 18) = 8 x 20 = 160
7 x 8 + 3 x 8 = 8 x ( 7 + 3) = 8 x 10 = 80
5 x 11 + 11 x 8 = 11 x ( 5 + 8) = 11 x 13 = 143
6 x 15 + 15 x 4 = 15 x ( 6 + 4) = 15 x 10 = 150
8 x 5 - 8 x 3 = 8 x ( 5 - 3) = 8 x 2 = 16
9 x 8 - 6 x 9 = 9 x ( 8 - 6) = 9 x 2 = 18
4 x 15 - 4 x 1 = 4 x ( 15 - 1) = 4 x 14 = 56
8 x 12 - 8 x 6 = 8 x ( 12 - 6) = 8 x 6 = 48
Sper ca te-am ajutat! ;)
