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.

1.5 × 101 nanometers.
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
