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?

Answer 1

\[\sqrt{25}=5\]an integer so rational

Answer 2

also
\[\sqrt4=2\] another integer

Answer 3

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

Answer 4

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?

Answer 5

it can't be written as a fraction?

Answer 6

it can't be written as a fraction correct

Answer 7

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

Answer 8
