Answer:
rational
Step-by-step explanation:
A repeating decimal is a rational number.
Repeating 6's has a value of 2/3, so this number is 6 2/3 = 20/3, a rational number.
We can simplify 2√5+3√5-√5 because they all have the same radical, √5. Now that we know this, we can imagine that there are no radicals, and that we are just adding numbers. This results in our expression being 2 + 3 - 1. This gives an answer of 4. Finally, we add the √5 to the 4 to get 4√5.
