Square root of pi is 1.77245385091. To study irrational numbers one has to first understand what are rational numbers. In short, rational numbers are whole numbers, fractions, and decimals — the numbers we use in our daily lives.

A number is rational if you can write it as a ratio of two integers, in other words in a form a/b where aand b are integers, and b is not zero. Clearly all fractions are of that form. Terminating decimal numbers can easily be written in that form, and also all non-terminating repeating decimals (decimals that repeat a sequence of digits) are rational. Easily, NON-repeating NON-terminating decimal numbers are IRRATIONAL NUMBERS.  Pi is approximately 3.14. In reality, Pi is an unending, never repeating decimal, which means it is an irrational number. Here are the first digits: 3.1415926535897932384626433832795.


Another example of an irrational number is square root of 2, whose first decimals are 1.4142135623730950488016887242097. Most square roots are irrational.
