Which statement is correct about 3a²b and 5ab²?

Answer and explanation

Correct answer: दोनों असमान पद हैं

The governing concept is the definition of like and unlike terms. Two algebraic terms are like terms only when they contain exactly the same variables, with each variable raised to the same power; their numerical coefficients may be different. In 3a²b, a has exponent 2 and b has exponent 1. In 5ab², a has exponent 1 and b has exponent 2. Since the corresponding exponents are different, the terms have different variable parts and are therefore unlike terms. Hence option C is correct. They are not constants because both terms contain variables. Their coefficients are 3 and 5, so option D is also false. They cannot be combined by ordinary addition as though they had the same algebraic form.
