Scientific notation:
To write an amount in scientific notation the amount is written as multiplication of exponent of 10. In the given case we are asked to write the GDP of Germany 3.65 trillion in Scientific notation. The GDP is given 3.65 trillion and 1 trillion = 1,000,000,000,000. So we can write it as follows:
= 3.65 * 1 trillion
= 3.65 * 1,000,000,000,000
= 3.65 * 10^12
Hence the GDP of Germany in 2008 is 3.65 * 10^12
