Question

What is 16,448 written in scientific notation?A.1.6448 x 10*3B.16.448 x 10*3C.1.6448 x 10*4D.1.6448 x 10*5

Answer 1

A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.

This means we want to rewrite our number as

`16,448=1.6448*10^n`

To find the corresponding power of 10, we divide the original number by the scientific notation version(without the power of 10).

`(16,448)/(1.6448)=10,000=10*10*10*10=10^4`

Then, rewritting our number in scientific notation, we have

`16,448=1.6448*10^4`

The correct answer is option C.
