Given:
[tex]555,621,000[/tex]
Consider the individual options and compare them with the given number.
A.
[tex]5.0\times10^9[/tex][tex]\text{Use }10^9=1,000,000,000.[/tex]
[tex]5.0\times10^9=5.0\times1,000,000,000[/tex]
[tex]5.0\times10^9=5,000,000,000[/tex]
We know that
[tex]5,000,000,000>555,621,000[/tex]
This option is correct.
B.
[tex]6.2\times10^7[/tex]
[tex]\text{Use }10^7=10,000,000.[/tex]
[tex]6.2\times10^7=6.2\times10,000,000[/tex]
[tex]6.2\times10^7=62,000,000[/tex]
We know that
[tex]62,000,000<555,621,000[/tex]
This option is not correct.
C.
[tex]5.55621\times10^7[/tex]
[tex]\text{Use }10^7=10,000,000.[/tex]
[tex]5.55621\times10^7=5.55621\times10,000,000[/tex]
[tex]5.55621\times10^7=55,562,100[/tex]
[tex]55,562,100<555,621,000[/tex]
This option is not correct.
D.
[tex]9.99\times10^6[/tex]
[tex]\text{Use }10^6=1,000,000.[/tex]
[tex]9.99\times10^6=9.99\times1,000,000[/tex]
[tex]9.99\times10^6=9,990,000[/tex]
[tex]9,990,000<555,621,000[/tex]
This option is not correct.
Final answer:
[tex]5.0\times10^9\text{ is greater than 555,621,000.}[/tex]
Option A is correct.
