How do you write a number in scientific notation? The proper format for scientific notation is a x 10^b where a is a number or decimal number such that the absolute value of a is greater than or equal to one and less than ten or, 1 ≤ |a| < 10. b is the power of 10 required so that the scientific notation is mathematically equivalent to the original number.

Why do we use scientific notation? The primary reason for converting numbers into scientific notation is to make calculations with unusually large or small numbers less cumbersome. Because zeros are no longer used to set the decimal point, all of the digits in a number in scientific notation are significant, as shown by the following examples.

## How do you write 2.0 in scientific notation?

If you wanted to express this sum in scientific notation, you’d write 2.0 x 103. Here’s how we made that conversion. When you use scientific notation, what you’re really doing is taking a small number (i.e., 2.0) and multiplying it by a specific exponent of 10 (i.e., 103).

## How do you write 400000 in scientific notation?

Why is 400,000 written as 4 x 105 in scientific notation?
