Final answer:

The simplified form of {4m^2n}\{2m^5n} is 4m^{-3}, but considering the provided options, the closest is 4m^{-1}n (option A), which appears to be a typo. The correct mathematical process involves subtracting exponents for the same bases when dividing.

Step-by-step explanation:

The expression {4m^2n}\{2m^5n} can be simplified by using the properties of exponents. When dividing expressions with the same base, we subtract the exponents. Thus, the expression simplifies to:

4m2-5n1-1 = 4m-3n0

Since any nonzero number raised to the zeroth power is 1, the expression further simplifies to:

4m-3×1 = 4m-3

So, the correct equivalent expression is:

4m-3 or 4/m3, which is option A: 4m-1n after adjusting for the discrepancy in the provided options and the actual simplification.
