Answer 2

Answer:

Here, like terms are,

     i) $7xy, 14yx$ and $3xy$

    ii) $-3y^{2}x, 7xy^{2}$ and $-xy^{2}$.

Here no unlike terms are present.

Step-by-step explanation:

Given : The terms are $7xy, -3y^{2}x, 7xy^{2}, 14yx, -xy^{2},3xy$.

To find : Classify the like terms and unlike terms.

Solution :

• The given terms are  $7xy, -3y^{2}x, 7xy^{2}, 14yx, -xy^{2},3xy$.
• We have to classify the like terms and unlike terms.
• Like terms are the terms with same variable with same exponential powers. Their coefficient can be different.

• Unlike terms have different variables.

       Ex. $x^{2}$ and $3x^{2}$ are like terms.

             $-5x^{3}$ and $2y^{2}$ are unlike terms.

• Here, like terms are,

     i) $7xy, 14yx$ and $3xy$

     ii) $-3y^{2}x, 7xy^{2}$ and $-xy^{2}$.

• Here no unlike terms are present.
