# How do you simplify 6/(a^-3b)?

$\frac{6 {a}^{3}}{b}$ would be the simplication of this.
In most cases, a "simplified form" of an expression has no negative exponents. Since $\frac{1}{a} ^ - 3$ can be rewritten as ${a}^{3}$, the most simplified form of this expression would be $\frac{6 {a}^{3}}{b}$.
