How do you find the sum of the polynomials mn^3 and mn^4?

Finding the Sum of the Polynomials

To find the sum of the two polynomials mn³ and mn⁴, we need to simply add them together.

Step-by-Step Calculation

1. Identify the two polynomials: mn³ and mn⁴.
2. Since both polynomials share the common factor ‘mn’, we can combine them quite easily.
3. The expression becomes: mn³ + mn⁴.

Now, we can factor out the common term:

Factoring the Common Term

Factor ‘mn³‘ from both terms:

• This gives us: mn³(1 + n).

So, the sum of the polynomials mn³ and mn⁴ is mn³(1 + n).

Final Summary

In conclusion, when you add mn³ and mn⁴, you get mn³(1 + n) as the result.
