Answer: The number was incorrectly converted.

Explanation: The error is in the sign of the power: -9

While [tex]1\cdot10^{-9}=0.000000001\\[/tex], the power should have been positive 9 because

[tex]1\cdot10^9=1,000,000,000[/tex]

So the correct conversion is as follows:

[tex]86130600000.0\rightarrow86.1306\cdot10^9[/tex]
