How many integer x between 1 to 10000000 will satisfy the equation given below
sqrt(x)+sqrt(sqrt(x))+sqrt(sqrt(sqrt(x)))+sqrt(sqrt(sqrt(sqrt(x))))=A
here A is an integral positive number
it the sum of first n terms of A.P is cn^2,then the sum of squares of these n terms is
(1)n(4n^2-1)/c^2/6 (2)n(4n^2+1)/c^2/3 (3)n(4n^2-1)/c^2/3 (4)n(4n^3+1)/c^2/6
