Answer 1

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

Answer 2

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:
 $4,540,000,000$
