9 billion written in scientific notation is: 9 x 10^9
It is: 1,560,000,000 or as 1.56*10^9 in scientific notation
It is: 7.5*10^9 = 7.5 billion in scientific notation
It is: 2,800,000,000 or as 2.8*10^9 in scientific notation
It is: 8.0*10^9 in scientific notation
1.0x10^9

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.
One billion is 1,000,000,000; 1 followed by 9 zeros. This is equal to 10 raised to the ninth power and would be written as 1×109 in scientific notation.
