1.Define [ n ] to be the greatest integer less than or equal to n.Compute the area of the
solution set of [ x ]・[ y ] = 2000.
2.If a and b are the roots of 11x2 – 4x – 2 = 0,then compute the product:
(1 + a + a2 + a3 + ...) (1 + b + b2 + b3 + ...)
3.Compute x/y in simplest terms if x + 1/y= 4 and y + 1/x = 1/4.
