# How do you simplify (3m^-4)/(m^3) and write it using only positive exponents?

$\frac{3}{m} ^ 7$
$\frac{3 {m}^{-} 4}{m} ^ 3 = \frac{3}{{m}^{3} \cdot {m}^{4}} = \frac{3}{{m}^{3 + 4}} = \frac{3}{m} ^ 7$
the ${m}^{-} 4$ goes to the bottom because of the negative-exponent rule ${x}^{-} n = \frac{1}{x} ^ n$
