Question

Which of the following are like terms?
$18x^2$$y^3$, $18x{y}^3$, $18x^2$y,
$17x^2$$y^3$

• A. $18x^2$y^3$and$17x^2$y^3$
• B. $18x^2$y^3$,$18xy^3$
• C. $18x^2$y^3$,$18x^2$y
• D. $18x{y}^3$, $18x^2$y

Answer 1

The correct option is A $18x^2$y^3$and$17x^2$y^3$

Like terms are the terms containing the same variabes raised to the same power. Their numeric coefficients need not be the same.
Hence, $18x^2$$y^3$ and
$17x^2$$y^3$ are like terms.
