2. How do you calculate powers of negative numbers, such as $(-5)^3$?
3. What are cube roots and how are they related to cubes?
4. Can you explain the difference between squaring a number and cubing it?
5. How is exponentiation applied in real-world situations?

Tip: When raising a number to a power, remember that it involves multiplying the base by itself as many times as the exponent indicates. For example, $6^3 = 6 \times 6 \times 6$.
