Identify the terms as like or unlike,

8r , 8r^{2}

**Solution:-**

To determine if terms are like or unlike, you can begin by writing each term as the product of its numerical coefficient and its variable portion.

8r = 8* r

8r^{2} = 8*r^{2}

Now look at the variable parts, r and r^{2}. If they are identical including the powers on the variable, then the terms 8r and 8r^{2 } are like terms. Otherwise, they are unlike terms.

The variable parts are not identical because one has an exponent of 2 and the other doesn’t.

Thus, the terms are unlike terms.
