Question

Given square root of 4 + square root of 25 and square root of 4 + square root of 2
is one or both rational or irrational?

anonymous · Answer

$$\sqrt{25}=5$$an integer so rational

anonymous · Answer

also 
$$\sqrt4=2$$ another integer

anonymous · Answer

only one that is not rational is $\sqrt2$ because 2 is not the square of a whole number

anonymous · Answer

Ok - so the first set is rational because both can be broken down evenly, but the second cannot because 2's square root is decimated?

anonymous · Answer

it can't be written as a fraction?

anonymous · Answer

it can't be written as a fraction correct

anonymous · Answer

not sure i have ever heard it called "decimated" before though...

anonymous · Answer

Thank you! :D
Lol...think I meant not a whole number
