$(-9)^{3}$
In algebra, exponents can be used to write products of repeated factors. Exponents take the form $a^{b}$, where $a$ is the repeated factor and $b$ is the amount of times that the factor is being multiplied by itself. In this case, -9 is being multiplied by itself 3 times. Therefore, $(-9)(-9)(-9)=(-9)^{3}$.
