The distance to the star Antares, which is approximately 604 light years away from Earth, can be expressed in scientific notation as (6.04 \times 10^2) light years. This format simplifies the representation of large numbers, making it easier to read and understand in scientific contexts.
The Great Galaxy in Andromeda (also known as the Andromeda Galaxy or M31) is about 2.5 million light years from Earth. When we look at this galaxy today, we see light that has been traveling through space for 2.5 million years; i.e. when we look at the Andromeda Galaxy, we are seeing it as it was about 2.5 million years ago! Think about this, we are looking back in time.1 light year is the distance that light travels in 1 year. Speed of light is 300,000 kilometers/second, find the distance that light travels from the Andromeda Galaxy to Earth in kilometers and express it in scientific notation.
Distances to other planets, other stars and other galaxies are very large, making measurements in meters or kilometers difficult to handle (although scientific notation can be used). As a result, astronomers have gotten accustomed to measure distance within the Solar System in astronomical units, and to other stars and galaxies, either in light-years or in parsecs.
1.5 million light-years is equivalent to the distance that light travels in 1.5 million years.
1 Parsec = 3.26163626 light years

Ypu have to use scientific notation to the 10th power
We don't know. The diameter of our galaxy is estimated at 100,000 lights years. But it is an estimate. When we look at the stars in the night sky, we are looking at how those stars were thousands, even hundreds or thousands of years ago.
One light year is approximately equal to seven trillion miles. So, 23 million light years is approximately equal to 161 quintillion miles. In scientific notation, that is 1.61 x 1020 miles.

You don't really. You can just as well use the SI unit of length - the meter - and express the numbers in scientific notation. But most people prefer the smaller numbers that appear when using light-years or parsecs.
