A rational number is a number that can be written as a fraction of two integers except when the denominator is zero Learn how to identify use and manipulate rational numbers with examples interactive sliders and fun facts The square root of 2 is not a rational number because its decimal never ends so we have no way to express it in the form of a common fraction There are many different sets of numbers that are commonly used throughout mathematics
You can show that sqrt 2 sqrt 3 is a zero of the polynomial x 4 10x 2 1 By the Rational Root Theorem the only possible rational roots of this polynomial are 1 and 1 So sqrt 2 sqrt 3 is irrational I m trying to do this proof by contradiction I know I have to use a lemma to establish that if x is divisible by 3 then x 2 is divisible by 3 The lemma is the easy part Any thoughts How should I extend the proof for this to the square root of 6
