Answer 2

Answer:

The number in scientific notation is $25,000,000,000,000=2.5\times 10^{13}$

Step-by-step 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,

$25,000,000,000,000=25\times 10^{12}$

$25,000,000,000,000=2.5\times 10^{13}$

Therefore, the number in scientific notation is $25,000,000,000,000=2.5\times 10^{13}$
