To determine how to write the GDP of Germany in 2008, which is 3.65 trillion, in scientific notation, let's break down the steps.
1. Understand the term "trillion":
- One trillion is equivalent to [tex]\(10^{12}\)[/tex].
2. Identify the number part:
- Here, the number given is 3.65.
3. Combine the number with the power of 10:
- Since 1 trillion is [tex]\(10^{12}\)[/tex], 3.65 trillion would be [tex]\(3.65 \times 10^{12}\)[/tex].
Hence, the correct answer is:
A. [tex]\(3.65 \cdot 10^{12}\)[/tex]
