How do you solve to find half life

I don't know what you mean...

Tick

The half life equation is given by:

\large{N = N_o\, \times\, 2^{-\(\frac{t}{t_{\frac12}}\)}}

With no other information, we cannot help any better.

tick, half-life is a term used in radioactivity. For example, a half life of 1 year means that a substance took 1 year to decompose to half the initial mass. In two years, the mass will be the mass after a year, divided by two. It's dividing by two each time.

Thanks for the explanation Unk !
