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.
Your answer is the second option or "sqrt36."
Hope this helps.
