Basic Exponent Rules
Explanation of basic exponent rules
Basic exponent rules are essential for simplifying and manipulating equations with exponents. These rules include the product, power, quotient, and zero exponent rules. The product rule states that you add their exponents when multiplying two numbers with the same base. The power rule states that you multiply the exponents when raising a power to another power. The quotient rule states that you subtract their exponents when dividing two numbers with the same base. Lastly, the zero exponent rule states that any number (except zero) raised to the power of zero is equal to 1. Understanding these rules is fundamental for solving equations with unknown exponents effectively.
