Respuesta :

[tex] \sqrt{25} [/tex]    = 5     (perfect square ⇒ rational)
[tex] \sqrt{225} [/tex]  = 15   (perfect square ⇒ rational)
[tex] \sqrt{78} [/tex]    = 8.831760866      (irrational)
[tex] \sqrt{59} [/tex]    = 7.681145748      (irrational)

A rational number can be expressed in the way a : b or [tex] \frac{a}{b} [/tex]
An irrational number cannot be expressed this way!

The two attachments are just worth looking at
