The expression \( P^q \) represents \( P \) raised to the power of \( q \), where \( P \) is the base and \( q \) is the exponent. This means multiplying \( P \) by itself \( q \) times, provided \( q \) is a positive integer. Mathematically:

\[
P^q = \underbrace{P \times P \times P \times \cdots \times P}_{q \text{ times}}
\]

### Special Cases:
1. If \( q = 0 \), then \( P^0 = 1 \), as long as \( P \neq 0 \) (the zero exponent rule).
2. If \( q = 1 \), then \( P^1 = P \).
3. If \( q \) is negative, say \( q = -n \), then \( P^{-n} = \frac{1}{P^n} \).

1. What happens when the exponent is negative or fractional?
2. How do you calculate \( P^q \) when \( q \) is a fraction?
3. What is the rule for multiplying two expressions with the same base?
4. How do you differentiate \( P^q \) if \( P \) and \( q \) are functions of \( x \)?
5. How does \( P^q \) behave if \( q \) approaches infinity?

**Tip:** When multiplying powers of the same base, you can add the exponents: \( P^a \times P^b = P^{a+b} \).
