Homework Help: How to derive formula for nucleus decay using this equation?

  1. Feb 10, 2016 #1
    1. The problem statement, all variables and given/known data
    The formula being derived is N=No*e^k*t, from the equation Nn=No/2^n where No is the initial number of particles and the lowercase n in the second equation is the number of half lives. The n in Nn just indicates the number of particles after so many half lives. You might also use the formula for the decay constant so feel free to.
    2. Relevant equations
    N=No*e^kt
    Nn=No/2^n
    k=-.693/t

    3. The attempt at a solution
    I haven't really made any meaningful progress so I leave it to you!
