Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

$\left(\frac{-2}{8}\right)^{3}$

Step-by-step explanation:

The exponential form is x^a where a is the constant.

The expression $\frac{-8}{512}$ can be written as $\frac{(-2)\cdot(-2)\cdot(-2)}{8\cdot8\cdot8}$.

In general the expression can be written as $x\cdot{x}\cdot{x}=x^{3}$.

Use the general fact to write the fraction in the exponential form.

$\frac{(-2)\cdot(-2)\cdot(-2)}{8\cdot8\cdot8}=\left(\frac{-2}{8}\right)^{3}$

Therefore, the exponential form is $\left(\frac{-2}{8}\right)^{3}$.
