Answer :

[tex]4540mln=4,540,000,000\\\\in\ scientific\ notation:4,\underbrace{540,000,000}_{\leftarrow9}=4.54\cdot10^9[/tex]
For this case what we should do is take into account the following conversion:
 [tex]million = 10 ^ 6 [/tex]
 We then have the following number:
 [tex]4540 million [/tex]
 Applying the given conversion we have:
 [tex]4540 * 10 ^ 6 [/tex]
 By doing the corresponding calculation we have that the standard form is given by:
 [tex]4540 * 10 ^ 6 = 4,540,000,000 [/tex]
 Answer:
 
4540 million in standard form is:
 
[tex]4,540,000,000[/tex]
