# Identify like terms in the following:

(a)-xy^{2}, -4yx^{2}, 8x^{2}, 2xy^{2}, 7y, -11x^{2}, -100x, -11yx, 20x^{2}y, -6x^{2}, y, 2xy, 3x

(b) 10pq, 7p, 8q, -p^{2}q^{2}, -7qp, -100q, -23, 12q^{2}p^{2}, -5p^{2}, 41, 2405p, 78qp, 13p^{2}q, qp^{2}, 701p^{2}

**Solution:**

Let's define like and unlike terms before proceeding.

Like terms are those terms whose variables and their exponent power are the same. The coefficient of these variables can be different. Unlike terms are those terms whose variables and their exponents are different from each other.

(a) Like terms are:

- - xy
^{2}, 2xy^{2} - - 4yx
^{2}, 20x^{2}y - 8x
^{2}, - 11x^{2}, - 6x^{2} - 7y, y
- - 100x, 3x
- - 11yx, 2xy

(b) Like terms are:

- 10pq, - 7qp, 78qp
- 7p, 2405p
- 8q, - 100q
- - p
^{2}q^{2}, 12q^{2}p^{2} - - 23, 41
- - 5p
^{2}, 701p^{2} - 13p
^{2}q, qp^{2}
