The distance between earth and one of the brightest stars in the night sky is 33.7 light-years. one light-year is 6,000,000,000,000 [6 trillion] miles , find the distance between the earth and the star in miles. write answer in scientific notation.

Answer 1

Answer: To find the distance between Earth and the star in miles, we need to multiply the number of light-years by the number of miles in a light-year.

33.7 light-years * 6,000,000,000,000 miles/light-year = 2.022 x 10^17 miles

So, the distance between Earth and the star is approximately 2.022 x 10^17 miles, written in scientific notation.
