The number 1 followed by 15 zeros is known as a quadrillion in the short scale system used in the United States and modern English-speaking countries. In the long scale system used in some European countries, this number is called a thousand billion. It is represented as 10^15 in scientific notation.
15/100000000 or 0.00000015 or 1.5 * 10^-7
one thousand million=15 billion 1 billion/ 15 billion = 1/15= 0.0666

A million billion in scientific notation is 1e+15 or 1 x 10^15
15 billion = 1.5 x 10^10 or 1.5e+10
4064.4 trillion in scientific notation is 4.0644 x 10^15
5880 trillion in scientific notation is written 5.88 x 10^15
To express 15 billion in standard form, you write it as (1.5 \times 10^{10}). This is because 15 billion is equal to 15,000,000,000, which can be simplified into this scientific notation format, indicating that the decimal point is moved 10 places to the left.

7 femtoseconds in scientific notation is 7 x 10^-15 seconds
It is: 3.0*10^15 in scientific notation
15 in Scientific Notation = 1.5 x 101
Scientific notation is usually used to represent large numbers (especially in astronomy). Take the example 15 million, 320 thousand...You could write it as 15,320,000 but a shorter way would be... 15.32 x 106
