Question

5) Calculează (a - b) * c = ?, ştiind că:
a= 9X 6-8 x 5
b= 50 - 6 X 7
c=1 x 4 + 10 x 0​

Answer 1

Răspuns:

a=9×6-8×5

a=54-40

a=14

b=50-6×7

b=50-42

b=8

c=1×4+10×0

c=4+0

c=4

=>(a-b)×c=(14-8)×4

=6×4=24

Answer 2

Răspuns:

a = 9×6-8×5 = 54-40 = 14

b = 50-6×7 = 50-42 = 8

c = 1×4+10×0 = 4+0 = 4

(a-b)×c = (14-8)×4 = 6×4 = 24
