Point (g,h) is on the circle represented by g^2+h^2=10, and g, h are integers. How many such points are possible?	Select
A) 0
B) 2
C) 4
D) 6
E) 8
g^2+h^2=10 and g, h are integers means that 10 is the sum of two perfect squares.   10 is the sum of only one pair of perfect squares 1 and 9.   So, there can be 8 such points, 4 in each quadrant:   (1, 3);   (1, -3);   (-1, 3);   (-1, -3);   (3, 1);   (3, -1);   (-3, 1);   (-3, -1).   Answer: 8.
