a3+b3=(a+b)3-3a2b-3ab2
It is equal to a^3 + b^3. It can also be expressed as (a + b)*(a^2 - ab + b^2) or (a^6 - b^6)/(a^3 - b^3) or many other expressions.
(a + b+ c)3 = a3 + b3 + c3 + 3a2b + 3ab2 + 3b2c + 3bc2 + 3c2a + 3ca2 + 6abc
The volume of Cube B is 216 cm3
9 cube !
(a+b)cube = a cube + b cube + 3a square b + 3ab square
a3+b3=(a+b)3-3a2b-3ab2
This is the formula: (a3)+(b3)=(a+b)(a2-ab+b2)
'a' minus 'b' whole cube is equal to 'a cube' minus 'b cube' minus (3 a square b ) plus (3 a b square) . .. .....thanks
(a + b)3 = a3 + 3a2b + 3ab2 + b3
It could be a^3 + b or (a + b)^3, depending on the context.
It is equal to a^3 + b^3. It can also be expressed as (a + b)*(a^2 - ab + b^2) or (a^6 - b^6)/(a^3 - b^3) or many other expressions.
(a + b+ c)3 = a3 + b3 + c3 + 3a2b + 3ab2 + 3b2c + 3bc2 + 3c2a + 3ca2 + 6abc
a3 + b3 + c3 + 2(a2)b + 2(b2)c + 2(a2)c + 2ab2 + 2(c2)b +abc
The volume of Cube B is 216 cm3
9 cube !
(a3-b3) = (a-b)(a2+ab+b2)
