Question from Joe: If the next closest galaxy is 15 quadrillion miles away and there are 8760 hours
|
Hi Joe,
e+12 means that you multiply by $10^{12},$
thus for example
\[5.5795 \mbox{e+6} = 5.5795 \times 10^6 = 5.5795 \times 100,000 = 5,579,500.\]
For the names I would look at Billions and More. On this page it says that $10^{12}$ is one trillion so 1.7123288e+12 is one point seven one two three two eight eight trillion or write it
1,712,328,800,000.
I hope this helps,
Harley
