Lcm of denominator will be abc
therefore a^3 + b^3 + C^3/abc = 3
according to identity of a+b+c = 0 then
a^3 + b^3 + c^3 = 3abc
3abc/abc = 3
therefore a^3 + b^3 + C^3/abc = 3
according to identity of a+b+c = 0 then
a^3 + b^3 + c^3 = 3abc
3abc/abc = 3

you must read property
if a+b+c=0
then
a^3+b^3+c^3=3abc
now to prove
take L.H.S
(a^3+b^3+c^3)/abc
by property numerator become 3abc
hence
L.H.S=R.H.S
if a+b+c=0
then
a^3+b^3+c^3=3abc
now to prove
take L.H.S
(a^3+b^3+c^3)/abc
by property numerator become 3abc
hence
L.H.S=R.H.S
