Answer: 7.8792*10^13


Explanation: We need to make a proportion to figure out the miles.

1 light year/5,880,000,000,000 miles=13.4 light years/x miles.

After cross multiplying (1 by x and 5800...by 13.4), we have x=7.8792*10^13

Also, the answer before setting it in scientific notation was 78.792 trillion and we moved the decimal 13 times to get to 7, which is between 1 and 10.
