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
[tex]16,448=1.6448\times10^n[/tex]
To find the corresponding power of 10, we divide the original number by the scientific notation version(without the power of 10).
[tex]\frac{16,448}{1.6448}=10,000=10\times10\times10\times10=10^4[/tex]
Then, rewritting our number in scientific notation, we have
[tex]16,448=1.6448\times10^4[/tex]
The correct answer is option C.
