Homework Statement
what is the identity of a3 + b3 + c3
i am getting a bit confused please help!
I don't know what you are asking. An identity is an equation that is always true. What you have isn't an equation, so can't be an identity.phymatter said:Homework Statement

Math identities are mathematical equations or expressions that are always true, regardless of the values of the variables involved. They are often used to simplify or solve more complex equations.
Math identities can be used when you are trying to simplify an equation or expression and you notice that it contains a pattern that matches a known identity. You can also use them when trying to prove the equivalence of two expressions.
Some common math identities include the distributive property, the commutative and associative properties, the Pythagorean theorem, and the quadratic formula.
It can be helpful to create flashcards or a cheat sheet with the most commonly used math identities. You can also practice using them in different equations to help solidify your understanding.
It can be useful to first identify the pattern or relationship between the terms in the equation. Then, look for a math identity that matches that pattern. It can also be helpful to simplify the equation as much as possible before applying a math identity.
