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 mean deviation of a^(3) + b^(3) "and" a^(3) - b^(3) (where a and b gt 0) is________.

a^(3)-9b^(3)+(a+b)^(3)

a^(3)+9b^(3)+(a-b)^(3)

Factorize a^(3)+(b-a)^(3)-b^(3) .

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))

If a^(3)+b^(3):a^(3)-b^(3)=133:117, Find a:b
