Answer to Question #25476 in Abstract Algebra for irfan
Moreover p and q are natural numbers.
After Squaring we have: p+q-2*sqrt(pq)=1
Then q=9, p=4.
In this expression p+q-sqrt (pq) the factor 2 is missing, actually it should be p+q-2*sqrt (pq).&
Thanks for correcting us!
i don't get it... because when we subst 9 and 4 to p+q-sqrt (pq) is not wqual to 1
