Question

Find like and unlike terms in the following expression.

$-5x^{2}z,\frac{7}{2}{x}^{2}z,2x{z}^2,z{x}^3$

Answer 1

Finding like and unlike terms

Two or more terms with identical variables with the same powers are called like terms.

Two or more terms that are not like called, unlike terms.

$$\begin{gathered} {\text{So ,like terms are -5x}}^{2}z,\frac{7}{2}{x}^{2}z \\ {\text{Unlike terms are 2xz}}^2,z{x}^3 \end{gathered}$$
