A population of lemmings doubles every 10 days. If there are initially 6 lemmings how many will there be in 60 days?

I'm really stuck with this problem. If any of you could help me out by explaining how to solve this I'd appreciate it! :)

I'm a bit confused, what exactly did you do?

because every 10 days we multiply x2 for the last time 12=6*2...

60/10 = 6 doublings

Future Population =6 x 2^6 =6 x 64 =384 lemmings after 60 days.
