how many miles in 3.2 x 10^2 light years?
hint ... multiply
A. 1.88 x 1012
B. 5.88 x 1014
C. 3.2 x 1015
D. 1.88 x 1015
I'm not sure what is being asked....
hint ... multiply
= about 18 * 10 ^14 miles = 1.8 * 10^15 miles
so yes D

this will give you a 87 it's not perfect but adleast you pass... sorry
(3.2 x 10^2) x (5.88 x 10^12) = 18.816 x 10^14
So, the approximate distance in miles is 1.88 x 10^15, which is option D. Now that is quite a distance! I hope the star has some good snacks for the journey!
First, you multiply the given distance of 3.2 x 10^2 light-years by the conversion factor:
3.2 x 10^2 light-years * 5.88 x 10^12 miles/light-year.
To multiply numbers in scientific notation, you multiply the coefficients (3.2 x 5.88) and add the exponents (2 + 12):
(3.2 * 5.88) x 10^ (2 + 12) = 18.816 x 10^14.
Since 18.816 is closer to 1.88 x 10^1 than 5.88 x 10^2, you can rewrite the answer in scientific notation as:
1.88 x 10^15.
So, the approximate distance in miles is 1.88 x 10^15 miles.
Therefore, the correct choice is option D. 1.88 x 10^15.
