Error: The error in Laila's solution is adding the exponents (10^13 + 10^12 = 10^25) instead of adding the actual GDP values of the US and the UK.
Correct Solution:
(1.313 x 10^13) + (1.93 x 10^12)
= 1.313 x 10^13 + 0.193 x 10^13 (converting the UK GDP to the same exponent as the US GDP)
= 1.506 x 10^13
Therefore, the combined GDPs of the US and the UK in 2006 was 1.506 x 10^13.
5. In 2006, the US had a Gross Domestic Product (GDP) of 1.313 x 10^13. The United Kingdom had a GDP of 1.93 x 10^12. What
were the combined GDPs of the US and the UK in 2006?
Incorrect Work/ Laila’s Solution Identify and Explain the error
(1.313 x 10^13) + (1.93 x 10^12)
1.313 + 1.93 = 3.243
10^13 + 10^12 = 10^25
The combined GDPs of the US and the UK in 2006 was
3.243 x 10^25.
