Answer:
[tex]\sqrt{2}[/tex]
Step-by-step explanation:
A rational number has the form
[tex]\frac{a}{b}[/tex] , where a and b are integers
Given
- [tex]\sqrt{2}[/tex] ( multiplying by [tex]\sqrt{2}[/tex] gives )
- [tex]\sqrt{2}[/tex] × [tex]\sqrt{2}[/tex]
= - 2
= [tex]\frac{-2}{1}[/tex] ← a rational number
