It is: 300,000,000
since 300 million is written as 300,000,000 you can rewrite it as 3 x 108.
3.0 × 108
0.3 billion = 300,000,000 (300 million)
It is: 300,000,000 or as 3.0*109 in scientific notation
It is 3*10^8
It is: 3.0*10^8 in standard form or scientific notation
300 is already in decimal notation.
300 in Scientific Notation = 3 x 102
5.300700553 x 109
300 in Scientific Notation = 3 x 102
Engineering notation changes every factor of 1000, so it corresponds to the SI prefixes (and names of large numbers). So 3 x 10^8 m/s becomes 300 x 10^6 m/s, or 300 megameters per second (or 300 million meters per second).
26.7 million in standard notation is 26,700,000
