1.9958*10^13 miles. Just multiply the number of light years by the number of miles in one light year to get this answer.

To solve, multiply 3.4x5.87=19.558
19.558x 10 to theee 12th power is the answer to this first step.
Then reducing to standard exponential notation give the final answer= 1.9558x 10 to the 13th power. (Sorry, I don't know how to print exponents on the computer)
