300000 = 10000 e^3k

30 = e^3k

3k = ln30

k = 1/3 ln30

P(t) = 10000 * e^(t/3 ln30)

P(4) = 10000 * e^(4/3 ln30) = 932170

Note that since e^ln30 = 30,

P(t) = 10000 * 30^(t/3)

but to evaluate that, you need to fall back to logs anyway.

What it means is that the population grows by a factor of 30 every 3 years. But then, we knew that from the initial conditions given: P(3) = 30*P()
