    Study Notes

    Exponent Rules & Practice

    • Product Rule: To multiply when bases are the same, keep the base and add the exponents. Example: x³ * x⁸ = x¹¹

    • Quotient Rule: To divide when bases are the same, keep the base and subtract the exponents. Example: x⁵ / x² = x³

    • Zero Exponent Rule: Any base (except zero) raised to the power of zero equals one. Example: y⁰ = 1, 6⁰ = 1

    • Power Rule: To raise a power to another power, keep the base and multiply the exponents. Example: (x³)⁴ = x¹²

    • Expanded Power Rule: When multiple factors are raised to a power, each factor is raised to that power. Example: (xy)² = x²y²

    • Negative Exponents: If a factor is moved from the numerator to the denominator (or vice versa), the sign of the exponent changes. Example: x⁻³ = 1/x³

    • Caution: An exponent only applies to the factor immediately next to it unless parentheses enclose other factors. Example: (-3)²=9, but -3²=-9

    Exponents Practice Problems and Solutions

    • Problem 1: 3 * 4³ = 192

    • Problem 2: 4x³ * 2x³ = 8x⁶

    • Problem 3: x⁵ * x³ / x⁻¹= x⁷ / x⁻¹ = x⁸

    • Problem 4: 2x³ * 2x²= 4x⁵

    • Problem 5: 6³ = 216

    • Problem 6: 8⁰ = 1

    • Problem 7: -(9x)⁰ = -1

    • Problem 8: (y⁴)³ = y¹²

    • Problem 9: (x²y)⁴ = x⁸y⁴

    • Problem 10: 2x⁴ / 4x² = x²

    • And many more problems are listed in the document
