Solution:

Given:


P(t)=(240)3^{(t)/(3)}

To reach 6480 alligators, this means when P(t) = 6480


\begin{gathered} 6480=(240)3^{(t)/(3)} \\ (6480)/(240)=3^{(t)/(3)} \\ 27=3^{(t)/(3)} \end{gathered}

Rewriting the equation in base 3,


\begin{gathered} 3^3=3^{(t)/(3)} \\ Equating\text{ the exponents,} \\ 3=(t)/(3) \\ Cross\text{ multiplying,} \\ t=3*3 \\ t=9years \end{gathered}

Therefore, it will take 9 years for the population to reach 6480 alligators
