Respuesta :

To find the distance in miles we have to multiply the distance in light years by it's equivalent in miles:

[tex]4.24\text{ light years}\cdot\times5.9\cdot10^{12}\text{ miles}\cdot=4.24\cdot5.9\cdot10^{12}=25.016\cdot10^{12}[/tex]

In correct scientific notation we have to move the decimal point one place to the right, so we add 1 to the exponent of 10:

[tex]2.5016\times10^{13}[/tex]

Proxima Centauri is 2.5016 x 10¹³ miles away from the Sun
