TEMĂ
1. Efectuați calculele, ştiind că a=4 si b=5.
a x (a - 2) x (a+4) =
bx (b+3) -(6-2) =
a x (b-3) x (b+1) =
bx (a-3) + (6-5) =​

Answer 1

Răspuns:

4x(4-2)x(4+4)=4x2x8=64

5x(5+3)-(6-2)=5x8-4=36

4x(5-3)x(5-1)=4x2x4=32

5x(4-3)+(6-5)=5x1+1=6

Answer 2

5×(5+3)-(6-2)=

5×8-4=

40-4=36

4×(5-3)×(5+1)=

4×2×6=

8×6=48

5×(4-3)+(6-5)=

5×1+1=

5+1=6
