14m^2n - 6m^2n =

14-6=8

8m^2n

Correct!

To simplify the expression 14m^2n - 6m^2n, you can combine the like terms, which means adding or subtracting coefficients that have the same variables raised to the same powers.

In this case, both terms have the variables m^2n with coefficients of 14 and -6 respectively. To combine these terms, you simply subtract the coefficients:

14m^2n - 6m^2n = (14 - 6)m^2n = 8m^2n

Therefore, the simplified expression is 8m^2n.
