1. The problem is to simplify the expression $$\frac{m^3}{m^5}$$ using only positive exponents. 2. Recall the rule for dividing powers with the same base: $$\frac{a^m}{a^n} = a^{m-n}$$. 3. Applying this rule, we get: $$\frac{m^3}{m^5} = m^{3-5} = m^{-2}$$. 4. To express with only positive exponents, use the rule $$a^{-n} = \frac{1}{a^n}$$. 5. Therefore, $$m^{-2} = \frac{1}{m^2}$$. Final answer: $$\frac{1}{m^2}$$
