Answer:
$80,000,000,000
Explanation:
The GDP of Switzerland is given as 8×10¹¹ dollars. To express this in standard form, we can move the decimal point 11 places to the right:
8×10¹¹ = $80,000,000,000
So, the approximate GDP of Switzerland is $80,000,000,000.
Therefore, the correct answer is:
$80,000,000,000
