Why not " We have three long days in front of us." Exactly the same meaning
I encountered this as well. I am reporting it.
I'ld suggest to just report it, if you haven't done so yet.
Still won't accept it and just made me lose at the last exercice... -.-'''
Has there been any movement on Duolingo learning to accept this? YES, today it accepted "We have three long days ahead of us"
I thought plural adjectives ended with -en? "...drei langen Tage..."?
So did I think it would be "...drei langen Tage".
Could someone please explain why "lange Tage".
