WebExponents are also called Powers or Indices. Let us first look at what an "exponent" is: The exponent of a number says how many times to use. the number in a multiplication. In … WebA negative exponent means how many times to divide by the number. Example: 8-1 = 1 ÷ 8 = 1/8 = 0.125 Or many divides: Example: 5-3 = 1 ÷ 5 ÷ 5 ÷ 5 = 0.008 But that can be done an easier way: 5-3 could also be calculated like: 1 ÷ (5 × 5 × 5) = 1/53 = 1/125 = 0.008 That last example showed an easier way to handle negative exponents:
