Question

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

Answer 1

The terms having the same literal coefficients are called like terms. They may differ only in their numeral coefficients
Given terms:$\frac{2}{3}xy,-4yx,2yz,\frac{-2}{3}yz,\frac{zy}{3}andyx$

Here, $\frac{2}{3}xy,-4yx,yx$ are like terms , as each has the same literal coefficient ${}^{\prime }x{y}^{\prime }$
Here,$2yz,\frac{-2}{3}yz,\frac{zy}{3}$ are like terms as each has the same literal coefficient$yz$

Therefore like terms in the given group are
$\frac{2}{3}xy,-4yx,yxand2yz,\frac{-2}{3}yz,\frac{zy}{3}$
