this problem is difficutl for me i have an answer but im unsure so if someone could check my answer please. heres my problem:

A light year is the distance that a light travels through a vacuum (space without matter) in one year. A light year is about 9.46 x 10^12km. The distance to the spiral galaxy NGC 4603 is about 1.08 x 10^8 light years. What is the distance in km?

Where is your answer to check? You just multiply them

distance= 9.46E12km/lightyears*1.08E8lightyears.

To solve this problem, you need to multiply the given distance in light years by the conversion factor to convert it to kilometers.

Given:
Distance to NGC 4603 = 1.08 x 10^8 light years
Conversion factor: 1 light year = 9.46 x 10^12 km

To find the distance in kilometers, multiply the given distance by the conversion factor:

Distance in km = (1.08 x 10^8 light years) * (9.46 x 10^12 km/1 light year)

To simplify, multiply the numbers and add the exponents:

Distance in km = 1.02 x 10^8 x 9.46 x 10^12 km

To multiply numbers in scientific notation, multiply the coefficients and add the exponents:

Distance in km = 9.6392 x 10^20 km

Therefore, the distance to the spiral galaxy NGC 4603 is approximately 9.6392 x 10^20 km.
