Răspuns:
patrate perfecte = 1, 4, 9, 16, 25
dar nu putem decat 1 si 4 deoarece daca folosim 9 vom avea abcd nu abc
(9 x 150= 1350)
cat = 1 cat= 4
cuburi perfecte = 1, 8, 27, 64, 125- rest
pt cat=1 abc = 150 x1 + 1= 151
abc= 150 x1 + 8 = 158 abc = 150 x1 + 27= 177
abc = 150 x 1 + 64=214 abc= 150 x1 + 125= 275
pt cat= 4 abc = 150 x 4 +1= 601
abc= 150x 4+ 8= 608 abc= 150 x 4 + 27= 627
abc= 150 x 4 + 64= 664 abc =150x 4+ 125= 725
