Exponent Rules 3C530C
1. The problem: Understand and describe the exponent rules.
2. Exponent rules are formulas that help us simplify expressions involving powers.
3. Key exponent rules:
- Product rule: $$a^m \times a^n = a^{m+n}$$ (when multiplying same bases, add exponents)
- Quotient rule: $$\frac{a^m}{a^n} = a^{m-n}$$ (when dividing same bases, subtract exponents)
- Power rule: $$(a^m)^n = a^{m \times n}$$ (power of a power, multiply exponents)
- Zero exponent rule: $$a^0 = 1$$ (any nonzero base to zero power is 1)
- Negative exponent rule: $$a^{-n} = \frac{1}{a^n}$$ (negative exponent means reciprocal)
- Power of a product: $$(ab)^n = a^n b^n$$ (distribute exponent to each factor)
4. These rules apply for any real number base $a \neq 0$ and integers $m,n$.
5. Using these rules helps simplify expressions and solve equations involving exponents easily.
Final answer: The exponent rules are the product, quotient, power, zero, negative exponent, and power of a product rules as described above.
