Question

3. ANALIZEAZĂ corectitudinea efectuării calculelor.
a = 9 + 9•[9+9• (9+9)]
b = 358 + 368 : (763: 7- 840 : 8) + 22 x 3
Cum e ,a" față de ,,b''

a=1548

b=561​

Answer 1

a = 9 + 9 x [ 9 + 9 x (9 + 9)]

a = 9 + 9 x (9 + 9 x 18)

a = 9 + 9 x (9 + 162)

a = 9 + 9 x 171

a = 9 + 1 531

a = 1 548

b = 358 + 368 : (763: 7- 840 : 8) + 22 x 3

b = 358 + 368 : (109 - 105) + 22 x 3

b = 358 + 368 : 4 + 22 x 3

b = 358 + 92 + 66

b = 450 + 66

b = 516

a > b
