ill send you a request and thank you
the square root of 25
the square root of 225
the square root of 78
the square rot of 59
thanks in advance

Answer 1

`√(25)` = 5 (perfect square ⇒ rational)

`√(225)` = 15 (perfect square ⇒ rational)

`√(78)` = 8.831760866 (irrational)

`√(59)` = 7.681145748 (irrational)

A rational number can be expressed in the way a : b or
`(a)/(b)`
An irrational number cannot be expressed this way!

The two attachments are just worth looking at
