Why was this mentioned?

Since some radicals are part of the Rational Number System {Q}, some radicals can be written as

  • fractions
  • terminating decimals
  • repeating pattern decimals

Example 4

Since other radicals are part of the Irrational Number System , these radicals can be expressed as decimal numbers that

  • do not have a pattern of repeating numbers
  • do not terminate
  • cannot be written as a fraction
