Exponent Rules 50Fae5
1. The problem: Understand the basic rules of exponents.
2. Rule 1: Product of powers with the same base
$$a^m \times a^n = a^{m+n}$$
This means when multiplying powers with the same base, add the exponents.
3. Rule 2: Quotient of powers with the same base
$$\frac{a^m}{a^n} = a^{m-n}$$
When dividing powers with the same base, subtract the exponents.
4. Rule 3: Power of a power
$$(a^m)^n = a^{m \times n}$$
When raising a power to another power, multiply the exponents.
5. Rule 4: Power of a product
$$(ab)^n = a^n b^n$$
Distribute the exponent to each factor inside the parentheses.
6. Rule 5: Power of a quotient
$$\left(\frac{a}{b}\right)^n = \frac{a^n}{b^n}$$
Distribute the exponent to numerator and denominator.
7. Rule 6: Zero exponent
$$a^0 = 1$$
Any nonzero number raised to the zero power equals 1.
8. Rule 7: Negative exponent
$$a^{-n} = \frac{1}{a^n}$$
A negative exponent means take the reciprocal of the positive exponent.
These rules help simplify expressions involving exponents and are fundamental in algebra.
