{(0.111)3+(0.222)3-(0.333)3+(0.333)3(0.222)} find the value

v     Solve this

{(0.111)³+(0.222)³-(0.333)³+(0.333)³(0.222)}

Answer

We know that a³+b³+c³ = 3abc

If a+b+c = 0

0.111+0.222-0.333 = 0

Therefore,

{3(o.111)(0.222)(-0.333)+ (0.333)³(0.222)}

{ -(0.333)³(0.222)+ (0.333)³(0.222)}

= 0

Hence o is the answer
