Explicație pas cu pas:

6 * (5 + 7) = 6 * 12 = 72

6 * (5 + 7) = 6 * 5 + 6 * 7 = 30 + 42 = 72

______________________________

9 * (4 + 6)  = 9 * 10 = 90

9 * (4 + 6)  = 9 * 4 + 9 * 6 = 36 + 54 = 90

_______________________________

2 * 41 + 2 * 71 = 2 * (41 + 71) = 2 * 112 = 224

2 * 41 + 2 * 71 = 82 + 142 = 224

_______________________________

2 * 48 + 2 * 71 = 2 * (48 + 71) = 2 * 119 = 238

2 * 48 + 2 * 71 = 96 + 142 = 238

_______________________________

10 * 22  +10 * 83 = 10 * (22 + 83) = 10 * 105 = 1050

10 * 22  +10 * 83 = 220 + 830 = 1050

________________________________

3 * 42 + 3 * 65 = 3 * (42 + 65) = 3 * 107 = 321

3 * 42 + 3 * 65 = 126 + 195 = 321

_________________________________

3 * 44 + 3 * 67 = 3 * (44 + 67) = 3 * 111 = 333

3 * 44 + 3 * 67 = 132 + 201 = 333

__________________________________

10 * 2 + 10 * 8 = 10 * (2 + 8) = 10 * 10 = 100

10 * 2 + 10 * 8 = 20 + 80 = 100

__________________________________

8 * 35 + 8 * 78 = 8 * (35 + 78) = 8 * 113 = 904

8 * 35 + 8 * 78 = 280 + 624 = 904

__________________________________

8 * 31 + 8 * 72 = 8 * (31 + 72) = 8 * 103 = 824

8 * 31 + 8 * 72 = 248 + 576 = 824

__________________________________

7 * 35 + 7 * 76 = 7 * (35 + 76) = 7 * 111 = 777

7 * 35 + 7 * 76 = 245 + 532 = 777

__________________________________

4 * 47 + 4 * 51 = 4 * (47 + 51) = 4 * 98 = 392

4 * 47 + 4 * 51 = 188 + 204 = 392

__________________________________

4 * 48  +4 * 59 = 4 * (48 + 59) = 4 * 107 = 428

4 * 48  +4 * 59 = 192 + 236 = 428

__________________________________

7 * 36 + 7 * 75 = 7 * (36 + 75) = 7 * 111 = 777

7 * 36 + 7 * 75 = 252 + 525 = 777

___________________________________

9 * 71 + 9 * 75 = 9 * (71 + 75) = 9 * 146 = 1314

9 * 71 + 9 * 75 = 639 + 675 = 1314

___________________________________

8 * 76 + 8 * 73 = 8 * (76 + 73) = 8 * 149 = 1192

8 * 76 + 8 * 73 = 608 + 584 = 1192

___________________________________

7 * 19 + 7 * 17​ = 7 * (19+17) = 7 * 36 = 252

7 * 19 + 7 * 17​ = 133 + 119 = 252
