Question

Calculează după model:
Model: (3 x 6) + (3 x 2) = 3 x (6 + 2)
= 3x8
= 24
a) (2 x 3) + (2 x 5) =
(5 x 4) + (5 x 6) =
(7 x 2) + (7 x 4) =
(8 x 3) + (8 x 5) =

Answer 1

Răspuns:

a.2×(3+5)=2*8=16

b.(5*4) +(5×6) = 5*(4+6) = 5*10 = 50

(7*2)+(7*4)= 7*(4+2) =7*6=42

(8*3) + (8*5)= 8*(3+5)=8*8=64
