Question

State whether each pair of the terms given below is like or unlike:

$5pq,7p^2{q}^2$

Answer 1

Check the terms are like or unlike.

Given, pairs are $5pq,7p^2{q}^2$

Two or more terms can be called as ‘like terms’ if they have

1. same variable
2. same degree

The given pairs $5pq,7p^2{q}^2$ can be called as unlike terms because these terms do not have the same degree and same variables together.

Although, they have same variables, they contain different powers for those same variables.

Hence, the terms $5pq,7p^2{q}^2$ can be called as unlike terms.
