Describe what is meant by like terms?

Like terms are terms in an algebraic expression that have the same variable raised to the same power. For example, (3x) and (5x) are like terms because they both contain the variable (x) with an exponent of 1. However, (3x^2) and (5x) are not like terms because their variables have different exponents. Combining like terms simplifies expressions by allowing you to add or subtract their coefficients.
