Question

the number of like terms in the expression -3a^2 x y+2 x ay^2-x^2+4ax^2y+7x^2y is class 8 pls answer my question ​

Answer 1

Answer:

None of the terms are like terms in the expression of

$-3a^{2} xy+2xay^{2} -x^{2}+4ax^{2} y+7x^{2} y$

under the condition that a hasn't been declared as a coefficient in the question. If it has been declared as such then the like terms of this expression are : $4ax^{2} y$ and $7x^{2} y$.

Step-by-step explanation:

In algebra, like terms are those terms in an expression where only the variables are the same. Same includes terms of all variables alike are similar even in the terms of raised power.

There are terms of $x^{2} y$ in the last two terms but 'a' is present in the second last one. Unless 'a' has been defined as a coefficient by the question; these two terms wouldn't fall under the category of like terms.
