Please help me I will give medals and fans.
amount left = original amount*(1/2)^(total time/length of half-life) so plugging in our numbers, we get: .25 = (1/2)^(t/45.1) solve for t
How to solve please help me
.25 = (1/2)^2 so (1/2)^2 = (1/2)^(t/45.1) 2 = t/45.1 solve for t
T= 45.1 x 2= 90?
90.2 but yeah
Any formula we need to use here please?
no, that's it, t = 90.2 years...
Days or years ?
A=Ao *m this not a decays formula ?or I confused !,
Ok thank you so much for helping
Please receive my appreciation.
Thanks for helping me.
I don't know how you do this steps .25= 1/2^t/45.1 1/2^2=1/2)^t/45.1
