Question

which pairs contain like terms?

$–2xyz,–3x^2{y}^2{z}^2$

Answer 1

Identifying $–2xyz,–3x^2{y}^2{z}^2$ are the like terms or not :

We know that the terms having same literal(variable) coefficient and their exponents such as the $2in{x}^2$ are the same are called like terms .

Since, $–2xyz,–3x^2{y}^2{z}^2$ not having same exponents.

Hence,$–2xyz,–3x^2{y}^2{z}^2$ are not like terms .
