Let p and q be distinct primes. Then the number of positive integer solutions of the equation `1/x+1/y=1/(pq)` is

Find the number of positive integral solution of the equation Tan^(-1)x+Tan^(-1)(1//y)=Tan^(-1)3 is

Q) The number ofpositive integer pairs (x, y) such that 1/x+1/y=1/2007 , x < y is

Q) The number ofpositive integer pairs (x,y) such that (1)/(x)+(1)/(y)=(1)/(2007),x

If p and q are distinct primes and x^(2)-px+q=0 has distinct positive integral roots p+q=?

p and q are distinct prime numbers and if the equation x^2 -px +q=0 has positive integer as its roots then the roots the roots of the equation are

Let p be a prime number and a be a positive integer.If p divides a^(2); then p divides a.
