When adding variables with the same exponents, you are combining terms that have the same variable raised to the same power. This is also known as "like terms."
Combining like terms is important because it simplifies an expression and makes it easier to solve. It also helps to avoid confusion and errors when working with more complex equations.
To add variables with the same exponents, simply add the coefficients of the terms with the same variables and exponents. The variable and exponent will remain the same in the simplified expression.
No, you cannot add variables with different exponents. In order to add terms, they must have the same variable raised to the same power. If the exponents are different, the terms are not considered like terms and cannot be combined.
If there are multiple variables with the same exponent, you can still combine them if they have the same variables and exponents. For example, 2x^2 and 3x^2 can be added to get 5x^2. However, if the variables or exponents are different, they cannot be combined and the expression remains in its original form.
