what is the total number of positive integral factors of (60)^5
A point (x,y) is called integral if both x and y are integers. How many points on the graph of 1/x + 1/y=1/4 are integral points?
The complex numbers 1+i and 1+2i are both roots of the equation
x^5- 6x^4+Ax^3+Bx^2+Cx+D=0
where A,B,C, and D are integers. What is the value of A+B+C+D?
