Find the common theme with all these numbers. ( Except for the fact that all of them are wrong )

242 + 32 = 450
252 + 567 = 1575
507 + 147 = 1200
1805 + 20 = 2205
570312 + 19208 = 798848

All the numbers in each line have a common factor which is then multiplied by a squared number. If these are cancelled throughout, onle the squared numbers are left - the sums are then made correct by removing the powers.
