Question

Among $x^3$, $4xy$, $3y^2$, $3x^2$ and $5xy$, which are like terms?

• A. $4xy$ and $3y^2$
• B. $3y^2$ and $3x^2$
• C. $4xy$ and $5xy$
• D. $3x^2$ and $x^3$

Answer 1

The correct option is C

$4xy$ and $5xy$

$4xy$ and $5xy$ are like terms since these expressions have the same variable $xy$.

Note that for two terms to be like terms, they should have the same variables, with each variable raised to the same power in each of the terms.

Hence $4xy$ and $5xy$ is the only set of like terms among the given ones.
