Answer:
It is irrational, & cannot be written as a fraction.
Step-by-step explanation:
[tex]\sqrt{2}[/tex] will give you a very odd number when plugged into the calculator.
1.414213562
With our knowledge of rational vs. irrational numbers, we know that means [tex]\sqrt{2}[/tex] has to be irrational because it is not a whole number, not an integer, & cannot be condensed into a fraction.
Any time you see a number that isn't a perfect square in a square root, it might be best to guess it is irrational.
Always plug it into a calculator (if possible) to check!
Hope this helps. :)
