Question

Which of the following pairs is/are like terms?
( a ) $x$ (b) $x^2$ (c) $3x^3$ (d) $4x^3$

• A. a , b
• B. b, c
• C. c, d
• D. a, c

Answer 1

The correct option is C c, d

Like algebraic terms are the terms who have the same variables but can have different constants.

For example: $2x$

$2$ is the constant and $x$ is the variable.

The power of the variable has to be exactly same for two like terms.

So, (c): $3x^3$ and (d): $4x^3$ has powers same i.e. $3$.

So, option C is correct.
