Question

15 Efectuează in două moduri, după model:
Exemplu: (6 + 12) x3 = 6x3 +1243 - 18+36-54
18 x 3 = 54
(22 + 14) X 3 =
(25 +125): 5 =
(45 - 12) x 4 =​

Answer 1

Răspuns:

(22+14)×3=

(22×3)+(14×3)=66+42=108

36×3=108

(25+125):5=

(25:5)+(125:5)=5+25=30

150:5=30

(45-12)×4

(45×4)-(12×4)=180-48=132

33×4=132
