Question

pune parantezele potrivite astfel să obții 3 rezultate diferite a)4x5:2+8=
b)3X4+5x2-14x3=​

Answer 1

a)4x5:2+8=

(4x5:2)+8= (20:2) + 8 = 10 + 8 = 18

(4x5):(2+8)= 20 : 10 = 2

b)3X4+5x2-14x3=

(3 × 4) + (5 × 2) - (14 × 3) = 12 + 10 - 42 = - 20

3 x [(4 + 5 x 2) - 14] x 3= 3 × [(4 + 10) - 14] × 3 = 3 × (14 - 14) × 3 = 3 × 0 × 3 = 0
