Question

Вычислите изпользуя распределительный закон номер 114

Answer 1

а) 37 * 12 + 37 * 88 = 37 * (12 + 88) = 37 * 100 = 3 700

б) 7 * 12 + 8 * 7 = 7 * (12 + 8) = 7 * 20 = 140

в) 37 * 12 - 37 * 2 = 37 * (12 - 2) = 37 * 10 = 370

г) 7 * 102 - 2 * 7 = 7 * (102 - 2) = 7 * 100 = 700

д) 28 * 9 + 22 * 9 = 9 * (28 + 22) = 9 * 50 = 450

е) 25 * 11 - 25 * 1 = 25 * (11 - 1) = 25 * 10 = 250

ж) 18 * 9 + 18 * 1 = 18 * (9 + 1) = 18 * 10 = 180

з) 25 * 99 + 25 = 25 * (99 + 1) = 25 * 100 = 2 500

и) 101 * 17 - 17 = 17 * (101 - 1) = 17 * 100 = 1 700

к) 41 * 50 - 50 = 50 * (41 - 1) = 50 * 40 = 2 000
