To write a number in scientific notation, move the decimal point to the right of the first digit in the number. Write the digits as a decimal number between 1 and 10. Count the number of places n that you moved the decimal point. Multiply the decimal number by 10 raised to a power of n.

How do you write 0.00001 in scientific notation?
We know that when we move the decimal to the right then $ b $ is negative. Thus, $ b = – 5 $ . Hence, the scientific notation of [0.00001] is $ 1 times {10^{ – 5}} $ .
What are the 4 rules of scientific notation?
Scientific Notation Vocabulary & Rules
| Rule #1 | The base is always 10 |
|---|---|
| Rule #3 | The absolute value of the coefficient is greater than or equal to 1 but less than 10 |
| Rule #4 | The coefficient carries the sign (+) or (-) |
| Rule #5 | The mantissa carries the rest of the significant digits |

How do you write 0.000189 in scientific notation?
Take the decimal point and move it to the right until you pass the first non-zero digit (in this case number 1 ) stop there and get rid of the zeros. Count the movements of the point and use this value as NEGATIVE power of 10 that you’ll use as a multiplicator. You get: 1.89 and 4 movements of the point.
