4 half lives...is the rest right?

1) 16 half lives... 2) 6000 years 3)96 000 years.. is that right

my test is in a few hours...if your planning on helping me out stop confusing me...you could help by telling me what the answer. thanks

therefore the answer to c) is 375 years.

375 years...my test is in 5 hours...can someone please just check my answer and if its wrong state the correct answer...i've been up all night...thanks

thanks hall of ivy...as for that below... there are 4 half lives...making it 8 years correct? The piece of wood starts with 32 g and eventually has only 2 g. It has 2/32= 1/16= (1/2)4 as much as originally. That means 32 is multiplied by 1/2 4 times. How many half-lives is that...

the number of half lives...my test is 2mr...can someone please answer it...its almost 2am and i don't get half life questions

hallsofIvy you never seem to help people out... anyways...n is the number of half-lives it has had...is that right Doc G or anyone else that is willing to help...

is that it? 32(\frac{1}{2})^{\frac{n}{6000}}

so what would the equation be?

still lost...i don't get it...im trying to do this correspondance and its very difficult

im lost...can someone show me how to do it...i need to study of this now...

we haven't done logs...this is suppose to be a remedial math...I'm looking for someone to answer it properly so I use this question to study from...Can someone please help me out...
