Răspuns

Explicație pas cu pas:

( abc + bca + cab ) / ( bac + acb + cba ) =  1

( 100 a + 10 b + c + 100 b + 10 c + a + 100 c + 10 a + b ) → numarator

_____________________________________________

( 100 b + 10 a + c + 100 a + 10 c + b + 100 c + 10 b + a ) → numitor

______________________________________________________

= ( 111 a + 111 b + 111 c ) / ( 111 b + 111 a + 111 c ) =

= 111 x ( a + b + c ) / 111 x ( a + b + c ) =

= 1
