The square root of 22 is NOT a rational number. There is no integer which when multiplied by itself gives 22. Thus, it is not a perfect square. A number is a rational number if it is the quotient of two integers. :)

Yes. It would be 21/2 * 91/2, or "three root two". Root two is an irrational number, so it's products - such as root 18, will be as well.

i thing o.91 is irrational because irrational number can not be written as a fraction they can only be written as numbers with Decimals

-9.1 is the ratio of -91 and ' 10 '. Completely rational. Hint: Any number that you can completely write down on paper with digits is rational.

As 91 = 7 × 13, √91 doesn't really simplify. It can be changed into: √91 = √(7×13) = √7 √13
