Which one of the following pairs of terms is composed of like terms? A. 4mn, 3my B. 2a, 2b C. - 3x, + 3y D. abc, cab

D. abc, cab

Step-by-step explanation:

We are given that some pairs of terms

We have to find the pairs of terms is composed of like terms.

Like terms : In algebra, like terms are those terms in which variables with power are same in the terms.

A. 4mn, 3my

In given pair, variables n and y are not same. Therefore, 4 mn and 3 my are not like terms.

B. 2a, 2b

In given pair variable a in first term and variable b in second term are not same. Therefore, given pair are not like terms.

C.-3x, 3y

Variable x and y are not same therefore, it is not the pair of like terms.

D. abc, cab

In given pair variable a with power is same in both terms, variable b with power is same in both terms and variable c with power is same in both terms. Hence, the pair is a pair of like terms.

Answer: D. abc cab.
