Calculati Dand Factor Comunplz Dau 5 Stele class=

Răspuns :

a)

Dam factor cumun 2021 :

2021*(1+35+64) = 2021*(36+64) = 2021*100=202100

b)

Dam factor comun 2021 :

2021*(68+32)+100*79 = 2021*100+100*79=100(2021+79)= 100(2100)=210000

Răspuns:

b. 202100

c. 210000

Explicație pas cu pas:

b.

2021 + 2021 × 35 + 2021 × 64 =

= 2021 × (1 + 35 + 64) =

= 2021 × 100 =

= 202100

c.

2021 × 68 + 2021 × 32 + 100 × 79 =

= 2021 × (68 + 32) + 100 × 79 =

= 2021 × 100 + 100 × 79 =

= 100 × (2021 + 79) =

= 100 × 2100 =

= 210000
