A rational number is any number that can be divided into a whole number by another whole number.
Let's try to see which of these square roots have a rational number.
First, let's try A.
√10 = 3.33~
This is irrational, as it has a repeating decimal, and cannot be divided into any whole number.
Now, let's try B.
√24 = 4.8979
This cannot be divided into a whole number by another whole number, so this is irrational.
Now let's try C.
√36 = 6.
This is a rational number, as 6 can be divided into a whole number by another whole number (6/2 = 3, 6/1 = 6).
Just to be sure, let's also try D.
√44 = 6.633249
This is irrational, as it cannot be divided into a whole number by another whole number.
Your answer is C.) √36.
I hope this helps!
