There's nothing to change here. There is no advantage or reason to write 7.060 in scientific notation. Technically, however, it could be written as 7.060 × 100, but this is not normally done.
7 billion is figures is
7,000,000,000
In scientific notation it is
7.0 x 10^(9).
Something that is a billion has 109. Therefore, 7,000,000,000 or 7 billion in Scientific Notation is 7.0 x 109
7.125 billion is 7.125 x 10^9
It is: 7.3*10^9
It is: 33,000,000,000,000,000,000 = 3.3*1019 in scientific notation.
It is: 6.8*10^10
It is: 2,608,000,000,000 = 2.608*1012
It is: 1.25*10^11
1.35 billion = 1.35 x 10^9 OR 1.35e+9
100 billion in scientific notation is: 1.000000e+11
80 billion in scientific notation is: 8.000000e+10
660 billion in Scientific Notation = 6.6 x 1011
Three billion in Scientific Notation = 3 x 109
Four billion in Scientific Notation = 4 x 109
6.32 billion in scientific notation is: 6.32 x 109
Five billion in Scientific Notation = 5 x 109
It is: 7.5*10^9 = 7.5 billion in scientific notation
40 billion in Scientific Notation = 4 x 1010
17 billion in Scientific Notation = 1.7 x 1010
2.68 billion in Scientific Notation = 2.68 x 109
4064.6 billion in scientific notation is 4 X 10^12
