Question

there are about 1x10^12 stars in our galaxy. there are about 10x10^12 galaxies in the universe. assuming each galaxy has the same number of stars, how many total stars are there in the universe

Answer 1

To find the total number of stars in the universe, we need to multiply the number of stars in our galaxy by the number of galaxies in the universe. Given that there are approximately 1x10^12 stars in our galaxy and 10x10^12 galaxies in the universe, we can calculate the total number of stars by multiplying these two numbers together.

Step-by-step explanation:

To find the total number of stars in the universe, we need to multiply the number of stars in our galaxy by the number of galaxies in the universe. Given that there are approximately 1x10^12 stars in our galaxy and 10x10^12 galaxies in the universe, we can calculate the total number of stars by multiplying these two numbers together.

1x10^12 stars/galaxy * 10x10^12 galaxies = 10x10^24 stars

Therefore, there are approximately 10x10^24 stars in the universe.
