Question

3. Fie a = 0,(3) și b = 3/2. Calculați a•b​

Answer 1

a= 0,(3) = 3/9= 1/3

b= 3/2

1/3× 3/2=1×3/3×2=3/6=1/2

Answer 2

Răspuns:

Explicație pas cu pas:

a = 0,(3) =>   a = (3/9)⁽³ = (3:3)/(9:3)  =>  a = 1/3

b = 3/2

_____________________________________

a × b = (1/3) × 3/2 = (1×3)/(3×2) = (3/6)⁽³ =(3:3)/(6:3) = 1/2
