How do you divide

25m^5n - 10m^4n + 15m^3n  /  5m^3n

Is the correct answer 5m2 - 2m + 3

Kristine D.

The equation was written as a fraction. No parentheses. The n is not part of the exponent.

I think it is fair to assume the problem was written as a fraction.

Evan,

You're right if the variable n is part of the exponent! It's hard to tell whether the equation was supposed to be:

25m5n - 10m4n + 15m3n / 5m3n      or

25m5n - 10m4n + 15m3n / 5m3n

Your answer is correct for the second equation, and I agree that it is the more likely problem.
