(xix)a^(3)+b^(3)+a+b

Prove that: (a-b)^(3)=a^(3)-b^(3)-3ab(a-b)

Prove that: (a+b)^(3)=a^(3)+b^(3)+3ab(a+b)

The value of 2a^(3)-[3a^(3)+4b^(3)-{2a^(3)+(-7a^(3))}5a^(3)-7b^(3)] is (a) -11a^(3)+3b^(3)( b) 7b^(3)+3a^(3)(c)11a^(3)-3b^(3) (d) (11a^(3)+3b^(3))

|A-B|!=0,A^(4)=B^(4),C^(3)A=C^(3)B,B^(3)A=A^(3)B then |A^(3) + B^(3) +C^(3)| = a)0 b)1 c) |A|^(3) d)63

If (2a - 3b)/(2a+3b) = 1/3 , then find the value of (2a^(3) - 3b^(3))/(2a^(3) + 3b^(3)) .
