4. Assume A+ 0 and is real, suppose f(t)=A e^{\left(\frac{4}{3} t\right)} Solve for t in the following equation f(t)=4 A \mathbf{A}\left[t=\frac{69}{2} \log (2)\right] \mathbf{B}\left[t=\frac{20}{3} \log (6)\right] \mathbf{C}[t=22 \log (12)] \mathbf{D}[t=2

\log (6)] \text { E }\left[t=\frac{3}{2} \log (2)\right] \text { F none of thege }
