Well, you have the half-life, so you can work out what the decay constant is. You can then use the nuclear decay law (equation) to work out initial activity
Hint: A=−dtdN=λN
So you can get the decay law in terms of A rather than N

This is from phy3 where that equation is not given. Isnt there a simpler way? Doing it ur way, do i sub in 12000 years as t? My calculator gives an error that way.

It's just one of those equations you're expected to know, I think. You should see the kind of thing I have to remember
And really? Mine doesn't... Got your units right?
I get about 1384 Bq, though I'm not really paying attention so there could be a calculator mistyping in there somewhere
