Question

VERIFICA EGALITATILE : 11*(8-5-2)=11*8-11*5-11*2+0:7*8 ; 8+9*10=(33:3*9+1)-100:10:5 ; 37+(45-6*6:6)=9*9-49:7

Answer 1

Răspuns:

Explicație pas cu pas:

11 × ( 8 - 5 - 2 ) = 11 × 8 - 11 × 5 - 11 × 2 + 0 : 7 × 8 ( A )

11 × ( 3 - 2 )       = 88 - 55 - 22 + 0 × 8

11 × 1                  = 11 + 0

11                        = 11   → Adevarat

____________________________

8 + 9 × 10 = ( 33 : 3 × 9 + 1 ) - 100 : 10 : 5 ( A )

8 + 90       = ( 11 × 9 + 1 ) - 10 : 5

98              = 100 - 2  → Adevarat

___________________________

37 + ( 45 - 6 × 6 : 6 ) = 9 × 9 - 49 : 7 ( Fals)

37 + ( 45 - 36 : 6 ) = 81 - 7

37 + ( 45 - 6 ) = 74

37 + 39          = 74 → Fals

       76 > 74

Answer 2

11×(8-5-2)=11×8-11×5-11×2+0:7×8

11×1=88-55-22+0

11=11 => Adevarat

8+9×10=(33:3×9+1)-100:10:5

8+90=(99+1)-2

98=100-2

98=98 => Adevarat

37+(45-6×6:6)=9×9-49:7

37+(45-1×6)=81-7

37+(45-6)=74

37+39=74

76=74 => Fals
