Evaluate : (313 x 313 + 287 x 287).
Choose the correct choice from the following choices:
A) 180338
B) 108338
C) 180383
D) 180833
E) None of them
(a^2 + b^2) = 1/2 [(a + b)^2 + (a- b)^2]   (313)^2 + (287)^2 = 1/2 [(313 + 287)^2 + (313 - 287)^2] = ½[(600)^2 + (26)^2]   = 1/2 (360000 + 676) = 180338.   180338nswer is 180338.
