Answer:
3n³/5m²
Explanation:
Given in the question an expression
3m^-2 / 5n^-3
we can separate them as
3 / 5 x m^-2 / n^-3
As we know the rule of negative exponents that any nonzero number raised to a negative power equals its reciprocal raised to the opposite positive power.
Here the negative exponents are -2 and -3
so, m^-2 =1 /m²
n^-3 =1 /n³
3 / 5 x n³/ m²
rearranging
3n³/5m²
