Which of the following pairs are like terms?

Answer and explanation

Correct answer: 4x और -7x

Like terms have exactly the same variables with the same exponents; their coefficients may differ. In 4x and -7x, the variable part is x, with exponent 1 in both terms, so they are like terms. In 5a and 5a², the exponents of a are 1 and 2, so they are unlike terms. Exam tip: Ignore the coefficients and compare only the variables and their exponents.
