Tja, man kan fort få den på formen:Aleks855 wrote:Ser mer ut som en trial-and-error oppgave. Også kjent som en programmeringsøvelse.
For hånd ville jeg nok gjort det som deg. Men et mot eksempel til det du skriver er for eksempel løsningenRealist1 wrote:
Med litt logikk, som at brøkene bør bli heltall, 12 og 13 ikke bør multipliseres med for store tall, etc, så kan man komme mye lengre.
