• A. Like: 4xy, 8x²
• B. Like: 4xy, 3yx
• C. Unlike: 4xy, 8x²
• D. Unlike: 3yx, 8x²

Answer 1

Answer: (A), (C)

The correct options are
A

Like: 4xy, 8x²

C

Unlike: 4xy, 8x²

Like terms contain the same variables raised to the same power whereas unlike terms are two or more terms that are not like terms, i.e. they do not have the same variables or powers.

Here, $3yx$ and $4xy$ are like terms.
$3yx$ and $8x^2$ are unlike terms.
$4xy$ and $8x^2$ are unlike terms.
$5xy$ and $3yx$ are like terms.
