Evaluating Exponents

An exponent is a number that tells how many times the base number is used as a factor. For example, 34 indicates that the base number 3 is used as a factor 4 times. To determine the value of 34, multiply 3*3*3*3 which would give the result 81.

Exponents are written as a superscript number (e.g. 34) or preceded by the caret (^) symbol (e.g. 3^4).

Some facts about exponents:

  • Zero raised to any power is zero (e.g. 05 = 0)
  • One raised to any power is one (e.g. 15 = 1)
  • Any number raised to the zero power is one (e.g. 70 = 1)
  • Any number raised to the first power is that number (e.g. 71 = 7)
