Simplify. Write the expression using only positive exponents.$m^{-2}\cdot n^3$m−2·n3​The simplified expression is .

To simplify the expression $m^{-2} \cdot n^3$ and write it using only positive exponents, follow these steps:

1. Identify the term with the negative exponent: $m^{-2}$.
2. Recall that a negative exponent indicates the reciprocal of the base raised to the corresponding positive exponent. Therefore, $m^{-2}$ can be rewritten as $\frac{1}{m^2}$.
3. Rewrite the entire expression using this information: $m^{-2} \cdot n^3 = \frac{1}{m^2} \cdot n^3$
4. Combine the terms into a single fraction: $\frac{n^3}{m^2}$

The simplified expression is $\frac{n^3}{m^2}$.
