-sqrt m^4n^7

-m^2 |n|^3 sqrt (n)

Step-by-step explanation:

-sqrt (m^4n^7)

We know that sqrt (ab) = sqrt (a) sqrt (b)

-sqrt (m^4) sqrt (n^7)

The sqrt (m^4) = m^2

The sqrt (n^7) = sqrt (n^6) sqrt (n) = |n|^3 sqrt (n) We take the absolute value because if n is negative, n^6 is postive, but n^3 is negative

-sqrt (m^4) sqrt (n^7)

-m^2 |n|^3 sqrt (n)
