Answer:
b
Step-by-step explanation:
Answer: option (b)
1 billion = 1, 000, 000, 000
In scientific notation, a number is rewritten as a simple decimal multiplied by 10 raised to some power n.
10 =101
100= 102
1, 000 = 103
1, 0000 = 104.
..............
Therfore 1 billion can be written as
1 billion =1, 000, 000, 000=10^{9}
Then 1.5 billion =  1.54 10^{9}
Hence option (b) is the correct answer
please give me brilliant answer
