Question

Arătați ca a=b in fiecare dintre cazurile: b)a=3,(3)+0,(6)
b=1,(2)+2,(7)

Answer 1

a=3,(3)+0,(6) = ( 33-3)/9 +6/9= 30/9+6/9=10/3+2/3=12/3=4

b= 1,(2)+2,(7)= (12-1)/9 +(27-2)9=11/9+25/9=36/9=4

a=b=4

Answer 2

a=(33-3)/9+6/9=30/9+6/9=(30+6)/9=36/9=12/3=4

b=(12-1)/9+(27-2)/9=11/9+25/9=36/9=12/3=4

a=b=4
