Verified Answer :

\(4540mln=4,540,000,000\\\\in\ scientific\ notation:4,\underbrace{540,000,000}_{\leftarrow9}=4.54\cdot10^9\)

For this case what we should do is take into account the following conversion:
 \(million = 10 ^ 6\)
 We then have the following number:
 \(4540 million\)
 Applying the given conversion we have:
 \(4540 * 10 ^ 6\)
 By doing the corresponding calculation we have that the standard form is given by:
 \(4540 * 10 ^ 6 = 4,540,000,000\)
 Answer:
 
4540 million in standard form is:
 
\(4,540,000,000\)
