Mystery Numbers (Posted on 2003-03-29) |
|
I have chosen 3 different whole numbers less than 10, and have found several simple combinations that lead to perfect squares. Calling the numbers x,y, and z, the following combinations all yield a perfect square as the answer. (A perfect square is a number that has a whole number square root).(x^2)y + (y^2)z + (z^2)xx+y+zz-y-xxyz(x^2)(z-1)There are also several more complicated arrangements that lead to perfect squares, such asx((z^2)-1)+z((y^2)-3)-x(yz-xy)2xz+x+zx((z^2)+x)+z(y^2)-(x^2)(z-y)Given that these perfect squares are all different, and range between 0 and 100 (inclusive), can you determine x,y, and z?
