Square Roots


Prove that the Square Root of 2

is an irrational number.

Discussion: That is, prove that this number can not be expressed as a rational fraction in lowest terms,

where the greatest common divisor of a and b is 1.



Show    irrational.


Use the Arithmetic Mean-Geometric Mean Inequality to develope an process for computing square roots of positive numbers.
