The expression you have provided is:

$0,2^{-3}$

This is equivalent to:

$\left( \frac{2}{10} \right)^{-3} = \left( \frac{1}{5} \right)^{-3} = \frac{1}{5^3} = \frac{1}{125}$

So, the result is:

$\frac{1}{125} \approx 0.008$

Would you like more details on this, or have any questions?

2. What is the difference between a positive and a negative exponent?
3. How does fractional base handling differ in exponents?
4. How do you simplify powers of fractions?
5. What are some real-life applications of negative exponents?

Tip: Negative exponents indicate reciprocal values. For example, $x^{-n} = \frac{1}{x^n}$.
