# How do you add variables with exponents?

Only add like terms.

Look for like terms. Terms must have exactly the same variables - and the same order of variables - before they can be added.

The same colors are used to display similar terms.

To add variables with exponents, you need to make sure that the variables have the same base and the same exponent. If they do, you can simply add or subtract the coefficients of those variables. If the variables have different exponents, you cannot directly combine them unless you simplify them first.

For example: [ 3x^2 + 5x^2 = (3 + 5)x^2 = 8x^2 ]

However, if you have terms like (3x^2) and (5x^3), you cannot directly combine them because they have different exponents. You would need to simplify each term individually or manipulate them to have the same exponent before you can combine them.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
