How do you write 0.0001 in scientific notation?
A scientific notation is a way to represent very large or very small numbers concisely, where a number is written in the form of power of 10.
Answer: The scientific notation for 0.0001 is 1 × 10-4.
All the numbers written in scientific notation are between 1 and 10 multiplied with powers of 10.
To convert any number to scientific notation, two rules are followed.
- The decimal will be shifted to the left whenever the given number is 10 or greater and the power of 10 is positive.
- The decimal will be shifted to the right whenever the given number is smaller than 1 and the power of 10 is negative.
The given number 0.0001 can be written as 0.0001 x 100in powers of 10.
Hence as per the first rule, to convert 0.0001 x 100 to scientific notation, we will shift the decimal to right and multiply with negative powers of 10 untill the number comes between 1 and 10.
Therefore, the scientific notation for 0.0001 is 1 × 10-4
