Question

If $15xy+16m{n}^2$ be added to $7ab+13p{q}^2$, is further simplification of the sum expression possible?

• A. Yes
• B. No

Answer 1

The correct option is B No

We have the first expression as $15xy+16m{n}^2$. It contains literal factors as $\underset{–}{xy}$ and $\underset{–}{m{n}^2}$.

We have the second expression as $7ab+13p{q}^2$. It contains literal factors as $\underset{–}{ab}$ and $\underset{–}{p{q}^2}$.

We can add or subtract the algebraic terms which contain the same literal factors. But in these two algebraic expressions, terms have different literal factors.

Adding the first expression to the second expression:
$(15xy+16m{n}^2)+(7ab+13p{q}^2)$



As all the terms(unlike terms) contain different literal factors, the above expression cannot be simplified further.

Therefore, option (b.) is the correct answer.
