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 terms. Like terms must contain exactly the same variables raised to exactly the same powers; their numerical coefficients may differ. In 3a²b, the power of a is 2 and the power of b is 1. In 5ab², the power of a is 1 and the power of b is 2. Since the corresponding powers differ, the terms cannot be combined directly and are unlike terms. Thus option C is correct. They are not constants because variables occur, and their coefficients 3 and 5 are not equal.
