Exponent Rules Simplified: A Quick Guide

  • Exponent rule one involves adding exponents when the bases are the same, as seen in 2^3 * 2^5 becoming 2^8.
  • Exponent rule two requires subtracting exponents when dividing with the same bases, like 3^8 / 3^2 resulting in 3^6.
  • For a base with an external number, the base remains unchanged, and the external number is multiplied with the exponent.
  • The simplest exponent rule states that any number to the power of 0 equals 1.
  • When multiplying with the same bases, the exponents are added, as in 2^3 * 2^5 = 2^8.
  • Dividing with identical bases involves subtracting the exponents, such as 3^8 / 3^2 = 3^6.
