Study Notes

Exponents

  • Definition: An exponent indicates how many times a base number is multiplied by itself.
  • Base: The number being multiplied.
  • Exponent: The small number written above and to the right of the base, indicating the number of times the base is multiplied by itself.

Rules of Exponents

  • x⁰ = 1, x ≠ 0: Any number raised to the power of zero equals 1, except for zero itself.
  • x¹ = x: Any number raised to the power of one is equal to itself.
  • xᵐ × xⁿ = xᵐ⁺ⁿ: When multiplying exponents with the same base, add the powers.
  • xᵐ ÷ xⁿ = xᵐ⁻ⁿ, x ≠ 0: When dividing exponents with the same base, subtract the powers.
  • (xᵐ)ⁿ = xᵐ×ⁿ: When raising a power to another power, multiply the exponents.
  • (xy)ᵐ = xᵐyᵐ: When raising a product to a power, apply the power to each factor.
  • (x/y)ᵐ = xᵐ/yᵐ, y ≠ 0: When raising a quotient to a power, apply the power to both the numerator and the denominator.
  • x⁻ᵐ = 1/xᵐ, x ≠ 0: A negative exponent indicates the reciprocal of the base raised to the positive value of the exponent.

Operations with Exponents

  • Multiplication: Multiply the bases together and add the exponents if the bases are the same.
  • Division: Divide the bases and subtract the exponents if the bases are the same.
  • Raising to a power: Multiply the exponents together.
  • Simplifying expressions: Use the rules of exponents to rewrite expressions in a simpler form.
