√99 = Square root of 99 = Irrational.

Rational # are able to be expressed as the ratio of 2 integers.

i.e. √25 = +5

5 = 5/1 = rational

Irrational # can not be expressed as a ratio of 2 integers.

It must be understood what is a rational number, and what is an irrational number. In addition, you must be familiar with the square root mathematical function. The square root function inquires into a number that when multiplied by itself

x amount of times, equals the original number under the square root. i.e. √81 = 9*9. So, the square root of 81 is 9, because 9 times 9 (itself) equals 81.

Now, in my latest example, √81 = 9, you realize the number 9, can be expressed as a ratio of 2 integers, (a whole number w/o decimal or fraction). 9/1 = 9. The original question, √99, does not have an even integer answer. √99 = 9.9498743.

And thus, 9.9498743 can not be rewritten as a neat ratio of two integers, which means that it is IRRATIONAL. If my written explanation is confusing, I suggest search Khan Academy's topic of Rational/Irrational numbers.

What else can I help you with?
