解題步驟

1. Understand the question

   show what you know
   a group of biologists tracked mice in a forest.
   they wrote the equation $n = 75 \\cdot 3^{t}$.

   • $n$ is the total number of mice.
   • $t$ is the years since the biologists counted.

   how many mice do the biologists predict will be in the forest after 4 years?

2. Explanation

   Step1: Substitute t=4 into equation

   $n = 75 \cdot 3^{4}$

   Step2: Calculate $3^4$

   $3^4 = 81$

   Step3: Compute final n value

   $n = 75 \times 81$

3. Final answer

   6075
