Iknow the answer but i need steps

1/ m×n^2

Step-by-step explanation:you first separate it as thism/m^2 × n/n^3so the m/ m^2 will give you 1/mAnd the n/n^3 will give you 1/ n^2so the numerator for both becomes 1 since 1×1= 1 and multiplying the denominator will give you m×n^2. Hence the general equation becomes 1/ m×n^2.

Answer is either b or c
