Answer:
![-3m^(12){n^(6) }](https://img.qammunity.org/2021/formulas/mathematics/middle-school/xigis4e8uq59tzr032uqcmg2n07gbw0sn6.png)
Explanation:
To begin simplifying this, we can first divide the coefficients, giving us:
![(-3m^(5)n^(4) )/(m^(-7) n^(-2) )](https://img.qammunity.org/2021/formulas/mathematics/middle-school/aiokntf8gy30zdx1v5x556as9c7eyw2hr4.png)
We know that when dividing exponents, this means we need to subtract the exponent on the denominator from the numerator. This gives us:
![(-3m^(5+7) n^(4+2) )/(1)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/imx02ota7tp9li4xffxjm6g8f6zqy8zprc.png)
Now, simplifying this gets:
![-3m^(12){n^(6) }](https://img.qammunity.org/2021/formulas/mathematics/middle-school/xigis4e8uq59tzr032uqcmg2n07gbw0sn6.png)
