14m^2 n^3 + 6 m^3 n^3 3m^2 n^3 =

ANSWER: 23m^6 n^9

Your answer makes no sense.

Are you not reading my and PsyDAG's replies?

Why are you changing exponents in addition?

Are you missing the + sign near the end of your expression?

no i not missing any this and the answer you have given me so far are not in the choices

To simplify the expression 14m^2 n^3 + 6 m^3 n^3 - 3m^2 n^3, we combine like terms by adding or subtracting the coefficients of the terms that have the same variables raised to the same exponents.

In this case, we have the terms:

14m^2 n^3
6m^3 n^3
-3m^2 n^3

Since all the terms have the same variables raised to the same exponents, we can add or subtract their coefficients.

Adding the coefficients:
14 + 6 - 3 = 17

So, the simplified expression is:
17m^2 n^3.
