Question

Group the like terms together​
(ii) $\frac{2}{3}xy,-4yx,2yz,\frac{-2}{3}yz,\frac{zy}{3}\text{and}yx$

Answer 1

The terms having the same literal coefficients are called like terms. They may differ only in their numeral coefficients.
Given terms: $\frac{2}{3}xy,4yx,yx$ are like terms as each has the same literal '$xy$'
Here, $2yz,\frac{-2}{3}yz,\frac{zy}{3}$ are like terms as each has the same literal '$yz$'.
Therefore, like terms in the given group are $\frac{2}{3}xy,-4yx,yx\text{and}2yz,\frac{-2}{3}yz,\frac{zy}{3}$.
