If 1/x - 1/y = - 29 and the value of (x +12xy - y) / (x - 6xy -y) can be expressed as m/n, where m and n are co prime positive integers. The value of m + n = ?
Prime number 31 can be expressed in the form n^5 -1, where n=2. Are there any other primes that can be expressed this way?
Find the largest possible value of positive integer N, such that N! can be expressed as the product of (N-4) consecutive positive integers?
x and y are distinct 2 digit numbers such that y is obtained by reversing the digits of x. Suppose they also satisfy x^2 - y^2 = m^2 for some positive integer m, then find the value of x+y+m?
