Răspuns :
a > b, a Λ b sunt consecutive.
a - b = 1, a = 1 + b.
aaa + 333² = 111bbb.
100a + 10a + a + 333² = 111bbb.
cum a = 1 + b.
100 ( 1 + b ) + 10 ( 1 + b ) + 1 + b + 333² = 111bbb.
100 + 100b + 10 + 10b + 1 + b + 333² = 111bbb.
111 + 111b + 333² = 111bbb.
111bbb = 100000 + 10000 + 1000 + 100b + 10b + b = 111000 + 111b.
111 ( b + 1 ) + 333² = 111000 + 111b.
111b + 111 + 110889 = 111000 + 111b.
111b + 111000 = 111000 + 111b.
