From a list of terms, Kavya picks only those that are like terms of 5x^2y: 3x^2y, 7xy^2, -2x^2y, 4x^2, 9yx^2. How many terms in her list are like terms of 5x^2y?

Question

Accepted Answer

3. Like terms need x^2 and y^1. 3x^2y yes, 7xy^2 no (powers swapped), -2x^2y yes, 4x^2 no (no y), 9yx^2 = 9x^2y yes. Count = 3.
