Question

(9+6)×100= 10×(1275-489)= (389+75)×10= 100×(3029-2978)= a=35×10+48:6-14×9 b=7×100-19-72:8 verifica egalitatea 2×a+b=2×(a+b)

Answer 1

La prima e 1. 234 2.654 3.163 4.643

Answer 2

(9+6)x100 = 15x100 = 1500
10x(1275-489) = 10x786 = 7860
(389+75)x10 = 464x10 = 4640
100x(3029-2978) = 100x51 = 5100

a=35x10+48:6-14x9 = 350+8-126 = 232
b=7x100-19-72:8 = 700-19-9 = 672
Verificam relatia 2xa+b = 2x(a+b)
2x232+672 = 2x(232+672)
464+672 = 2x904
1076=1808
A si b nu verifica egalitatea data.
