A light year, the distance light travels in 1 year,is approximately 5.9x10^12
Alpha centauri A,b 4.3
How far in miles is Alpha Centauri A,B. Scientific notation!
I thought the answer was 25.37 x10^12
To calculate the distance in miles to Alpha Centauri A and B, you need to multiply the distance of Alpha Centauri A and B in light years by the conversion factor. The conversion factor for light years to miles is approximately 5.88 x 10^12 miles per light year.
Let's calculate:
Distance to Alpha Centauri A,B = (Distance in light years) x (Conversion factor)
Distance to Alpha Centauri A,B = (4.3 light years) x (5.88 x 10^12 miles per light year)
To multiply the numbers in scientific notation, you can multiply the coefficients (4.3 x 5.88) and then add the exponents (10^12).
First, multiply the coefficients:
4.3 x 5.88 = 25.284
Next, add the exponents:
10^12
Therefore, the final answer is 25.284 x 10^12 miles.
Note: In scientific notation, we typically express the coefficient as a number between 1 and 10. So, to write the answer in scientific notation, we can convert 25.284 to a number between 1 and 10. In this case, we can move the decimal point one place to the left to get 2.5284 and then multiply it by 10^13 to maintain the same magnitude.
So, the final answer in scientific notation is approximately 2.5284 x 10^13 miles.
