Question

The approximate distance between our solar system and Alpha Centauri(the nearest star) is 25,000,000,000,000 miles. Express the number in scientific notation.

Answer 1

The distance would be 2.5 x 10^13 miles

Hope that helps!

Answer 2

The number in scientific notation is
`25,000,000,000,000=2.5* 10^(13)`

Explanation:

Given : The approximate distance between our solar system and Alpha Centaur (the nearest star) is 25,000,000,000,000 miles.

To find : Express the number in scientific notation ?

Solution :

The scientific notation is defines ad writing a number into smaller way or writing in terms of powers of 10.

Number - 25,000,000,000,000

It has already 12 zeros and add one zero to place a decimal,

`25,000,000,000,000=25* 10^(12)`

`25,000,000,000,000=2.5* 10^(13)`

Therefore, the number in scientific notation is
`25,000,000,000,000=2.5* 10^(13)`
