How do you prove a3 b3?
What is the formula for (a3 – b3)?
- Answer: (a3 – b3) = (a – b)(a2 + b2 + ab) Let us prove this by considering a = 4 and b= 2 then. (43 – 23) = (4 – 2)(42 + 22 + 4 × 2) LHS = (2)(28)
- LHS = 56. RHS = (a – b)(a2 + b2 + ab) RHS = (4 – 2)(42 + 22 + 4 × 2)
- RHS = 56. ∴ LHS = RHS. (a3 – b3) = (a – b)(a2 + b2 + ab) Hence the proof.

What is AUB math?
The union of two sets A and B is a set that contains all the elements of A and B and is denoted by A U B (which can be read as “A or B” (or) “A union B”). A union B formula is used to find the union of two sets A and B.
What is a B in set?
The Cartesian product of two sets A and B, denoted by A × B, is defined as the set consisting of all ordered pairs (a, b) for which a ∊ A and b ∊ B. For example, if A = {x, y} and B = {3, 6, 9}, then A × B = {(x, 3), (x, 6), (x, 9), (y, 3), (y, 6), (y, 9)}.
