1900 190 + 19 -------- 2109
It is: 1.9*10-2
It is 19/7170000000.However, it is probably better to use the standard form: 19/(7.17*10^9).

The standard form is 361 (19 x 19 = 361).
It is 19/7170000000.However, it is probably better to use the standard form: 19/(7.17*10^9).
3 billion 19 in standard form = 3.000000019 × 109The standard notation = 3,000,000,019
To express 38 in exponential form, we can write it as (38 = 2 \times 19). Since 2 and 19 are both prime numbers, we cannot simplify this further. Therefore, we can express 38 as (2 \times 19) in exponential form.
