How many pairs of positive integers x and y satisfy the equation xy = 20132013 ? How many pairs of positive integers x and y satisfy the equation xy = 20122012?
Look at this webpage.
It tells you that there are 24 divisors. So what is the answer?
If you are talking about ordered pairs (x, y) such that xy = n, then their number equals the number of divisors of n, which is denoted by d(n) or . According to Wikipedia, if for prime 's, then .
How many pairs of positive integers x and y satisfy the equation x^y = 2013^2013 ? How many pairs of positive integers x and y satisfy the equation x^y = 2012^2012?
Sorry, I think I didn't make the question clear...

Sorry, I think I didn't make the question clear... It not just divisor.
