Answer:
Step-by-step explanation:
Like terms are the terms which have the same variable and same exponent. It is not necessary that the coefficient is equal.
For example ab and 4ab are like terms because both the expression have the same variable a, b and exponent is also equal.
Looking into the given options, we can conclude that the expressions 2xy, -xy,1/2xy are like terms.
Hence, the like terms are
