(a). 

Here, we have to write 673,104 in scientific notation.

So, 673,104 =  6.73104 x 10⁵

 

(b).

population of the United States =  325.7 million or 3.257 * 10^8

Now, dividing 3.257 * 10^8 by 6.73104 x 10⁵, we get

 3.257 * 10^8/6.73104 x 10⁵

= 480 

 

Thus, Population of United States is 480 times larger than Detroit.
