Mathematics

Answer:

Irrational

Step-by-step explanation:

A rational number can be expressed as a ratio of two integers , p and q of the form \[\frac{p}{q}\]

So following are examples of rational numbers:

  • \[\frac{1}{2}\] is a rational number
  • \[\frac{3}{4}\] is a rational number
  • 2 is a rational number as it can be expressed as \[\frac{2}{1}\]

On the other hand , any number which cannot be expressed in this form is called an irrational number. For example:

  • \[\sqrt{2}\]
  • \[\sqrt{3}\]
  • \[-\sqrt{127}\]
