Question 566809
<font face="Times New Roman" size="+2">


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \sqrt{x}]


The the symbol is called a radical and the *[tex \Large x] inside of it is called the radicand.  The whole thing represents the positive number that when multiplied by itself results in the radicand.  That is to say:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \sqrt{x}\,\cdot\,\sqrt{x}\ =\ x]


Unless *[tex \Large x] is a perfect square, that is a number like 4, 25, or 15,241,383,936 (which is 123,456 * 123,456), then the result of taking the square root of *[tex \Large x] will be an irrational number.  Irrational numbers are numbers that cannot be expressed as the quotient of two integers.

My calculator said it, I believe it, that settles it
