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.

Explanation:

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
