Thanks, yes, keeping it simple, I just used a chart until I got down to 25 in 75 years.
thanks again
exponential decay of radioactive material:
the half life of a radioactive material is 25 years
started with 200 mg of material
how many years will it take to be left with 25 mg
t/n
M=C(½)
M = final mass
C = original mass
½ = decay factor
t = time
n = half life
How do you isolate the fractional exponent?
(this is a grade 9 math question - we are not familiar with logarithms yet - maybe I am making this too complicated.... )
