13 Million in Scientific Notation
Question: How do you write 13 million 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 13 million is 1.3 × 107.
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 13 million can be written as 13000000 and 13.0 × 106 in powers of 10.
Hence as per the first rule, to convert 13.0 × 106 to scientific notation, we will shift the decimal to left, which is 1.3 × 107
Therefore the scientific notation for 13 million is 1.3 × 107.
