I believe that there is an error on this page. In the "Method" section it states that "... in such a way that the exponents of the primes on the right-hand side are all even...". That statement is true. But in the mathematical description one line below it shows the sum of the exponents to be even, a weaker statement. The algorithm relies on each exponent of the prime factors being even, so that the number is a perfect square.
