geerky42 (geerky42):

Which number inside square root is not square number? That would be your irrational number.

OpenStudy (texaschic101):

irrational numbers are numbers that cannot be written as fractions....repeating decimals are also irrational

OpenStudy (loser66):

The way to calculate is take the inside number divided by 2,3,5,.... , if at the end you still have something inside the square root, then that number is irrational. For example |dw:1430340684847:dw|
