# What is 20 000 in Scientific Notation?

Scientific notation is a way of writing very large or very small numbers in a more concise way. It is often used in mathematics, physics, chemistry, and other sciences. In scientific notation, numbers are written in the form of a number between 1 and 10, multiplied by a power of 10. For example, the number 20 000 can be written in scientific notation as 2 x 104.

## How to Convert 20 000 to Scientific Notation To convert a number to scientific notation, first you need to determine the power of 10. To do this, count the number of digits to the left of the decimal point. In this case, the number 20 000 has 5 digits, so the power of 10 is 105. To convert the number to scientific notation, divide the number by 105 and multiply it by 10. In this case, 20 000 / 105 = 2 x 104.

## Advantages of Using Scientific Notation Scientific notation is useful when dealing with very large or very small numbers. It makes calculations easier and more efficient. For example, if you need to multiply two large numbers, such as 3 x 109 and 4 x 107, it is much simpler to do the calculation in scientific notation than it is in standard notation. In scientific notation, the calculation would be 3 x 109 x 4 x 107 = 12 x 1016. In standard notation, the calculation would be 3 000 000 000 x 40 000 000 = 120 000 000 000 000.

## Disadvantages of Using Scientific Notation Scientific notation can be confusing for people who are not familiar with it. It also requires the use of powers of 10, which can be difficult to calculate. In addition, some calculations, such as division, are more complicated in scientific notation than they are in standard notation.

In conclusion, scientific notation is a useful way of writing very large or very small numbers. It makes calculations easier and more efficient. However, it can be confusing for people who are not familiar with it, and some calculations can be more complicated than in standard notation. 20 000 in scientific notation is 2 x 104.
