Question

Which of the following is not a like term of $2x^{2}yz$?

• A. $4x\times xy\times z$
• B. $2x\times y\times z$
• C. $3x^2\times yz$
• D. $x^{2}y\times 7z$

Answer 1

The correct option is B

$2x\times y\times z$

$4x\times xy\times z=4x^{2}yz$
$2x\times y\times z=2xyz$
$3x^2\times yz=3x^{2}yz$
$x^{2}y\times 7z=7x^{2}yz$
$2xyz$ and $2x^{2}yz$ do have same variables but not raised to the same power. So they are not like terms.
