15 Seerosen
Auf einem 8 ha großen See befindet sich ein 100 m2 großes Feld von Seerosen. Jährlich
verdoppelt sich diese Fläche. Wenn ein See vollständig mit Seerosen bedeckt ist, stirbt
er. Wann ist der See vollständig bedeckt? Wann ist er halbvoll bedeckt?
Als er halbvoll bedeckt ist, bemerkt eine Spaziergängerin: „Oh, wie schön, diese Seerosen!“
Was würdest du ihr erzählen? Nimm Bezug zum Zitat von Hoimar von Ditfurth.

Ответ:
-2
Step-by-step explanation:
First, when you plug in -2, you have to put parentheses around it which you probably didn't do which is why you got it wrong. First calculate (-2)^4 then multiply the product by the rest of the expression. (-2)^4= 16. Now multiply 16 by -0.125 which is equal to -2.
