Answer:

Second option

Explanation:

Given the following question:

We are given four choices and we need to determine which choice is a rational number. In order for any integer to be a rational number you have to be able to write it as a fraction.

In this case, options one and four are immediately excluded since they are repeating decimals. They cannot be written as a fraction which leaves us with the second option or the third option.


√(36)

√(36) =6*6

=6=(6)/(1)

=(6)/(1)

Your answer is the second option or "sqrt36."

Hope this helps.
