Also diesesmal wird es eher kein rätsel sein sondern ein logisch denken test :P
Zum warm werden mal:
1) (1+1)³=?

2) (a+b)^5 Es sind NUR die Koeffizienten gefragt+erklärung wie man darauf gekommen ist, auswendig wissen zählt nicht!!

3) (a+b)^23 diesesmal sind die koeffizienten nicht gefragt weil das wäre ja ne reine quälerei^^

da das ziemlich einfach ist, wird die lösung schon in 4tagen verraten.

eure lösungen bitte nur per PN an mich. Ihr wollt es den anderen ja nicht verderben oder? :P

Taschenrechner darf NICHT verwendet werden!

EDIT: wer mir die lösung geschickt hat schreibt bitte was in den thread rein, damit man weiß wer schon alles mitgemacht hat!
EDIT2: ^ bedeutet hoch. z.B. a²=a^2
EDIT3: nochmal zur clarification: bei 3) muss man nur die variablen+exponenten angeben!

Auflösung:
1) (1+1)³=?
a³+3a²b+3ab²+b³
1+3*1+3*1+1=8

2) (a+b)^5 Koeffizienten
Der Trick heißt Pascalsches Dreieck

3) (a+b)^23 Basis+Exponent
Ok der Trick hier ist ganz einfach:
Die erste Zahl ist a^23 b^0, dann kommt a^22 b^1, a^21 b^2
Ok hier sieht man gut dass die erste basis immer eins abnimmt und die zweite immer um eines steigt bis b^23 kommt

1)

Da hätte ich 1+1 gerechnet und dann: 2x2x2 = 8 :o
