Question

Alcatuiti si rezolvati 18exerciti dupa model 27x(115+286)=

Answer 1

20 x ( 7+3 ) = 20 x 10 = 200
4 x ( 155+5 ) = 4 x 200 = 800
8 x ( 9+9 ) = 8 x 18 = 144 
77 x ( 9+1 ) = 77 x 10 = 770
12 x ( 222+222 ) = 12 x 444 = 5328
2 x ( 666+4) = 670 x 2 = 1340
0 x (1414 + 300 ) = 0 x 1714 = 0 
28 x( 1 + 19 ) = 28 x 20 = 560
11 x ( 11 + 1 ) = 11 x 12 = 132
