Because otherwise you will have a number that is really, really long like 29,000,000,000 when you could just have a simpler thing like 2.9 x 10^10.

How does scientific notation give you the strength of a super-hero?
when you work with scientific notation you get to use the powers of ten
What is a proper notation?
Notation is simply the process of writing something down in some kind of format; for example, scientists have a particular technique for writing numbers which is called scientific notation, which makes use of powers of ten. So instead of writing 13,000,000 a scientist would write 1.3 x 10^7.
Steps multiplying and adding scientific notation?
To add or subtract two numbers in scientific notation:Step 1: Adjust the powers of 10 in the 2 numbers so that they have the same index. (Tip: It is easier to adjust the smaller index to equal the larger index).Step 2 : Add or subtract the numbers.Step 3 : Give the answer in scientific notation.To divide numbers in scientific notation:Step 1 : Group the numbers together.Step 2 : Divide the numbers.Step 3 : Use the law of indices to simplify the powers of 10.Step 4 : Give the answer in scientific notation.To multiply numbers in scientific notation:1.

Why would you use scientific notation to express 35 nm in meters?
In scientific notation it is 3.5*10-8 metres whereas otherwise it is 0.000000035 metres. It is much easier to make a mistake in writing or reading the second form.
When writing twenty one and a half trillion in scientific notation what is the exponent needed on the base ten?
In those countries that use the long scale (based on powers of a million) eg Europe:1 trillion = million3 = 1018 ⇒ 211/2 trillion = 2.15 x 1019, ie exponent is 19.In those countries that use the short scale (based on powers of a thousand), eg USA:1 trillion = thousand x thousand3 = 1012 ⇒ 211/2 trillion =2.15 x 1013, ie exponent is 13.

What is the form of using numbers using powers of ten?
The form that uses only powers of ten are logarithms to base 10. The scientific notation does use powers of ten but the original number is also used in this representation.
Why is ten used in scientific notation?
Because we use the decimal system for counting.
Why is ten always the base for scientific notation?
It's probably in base ten because we use base ten for all our OTHER work in numbers as well. We learn to write numbers in base ten when in elementary school, and use base ten throughout our lives even if we aren't scientists or mathematicians or students or professionals who need to use scientific notation. So keeping scientific notation in base ten makes it easier for everyone to learn and read.
How do you demonstrate mathematical skills in the use of scientific notation and significant digits?
Scientists have developed a shorter method to express very large numbers. This method is called scientific notation. Scientific Notation is based on powers of the base number 10.The number 123,000,000,000 in scientific notation is written as :
Why is 10 used as the base in scientific notation?
The choice of 10 as the base in scientific notation is mainly due to historical reasons and the fact that humans use a decimal system in everyday life. Using base 10 in scientific notation allows for easy conversion between powers of 10 and ordinary numbers, making calculations and comparisons more intuitive. Additionally, the vast majority of scientific measurements and quantities tend to fall within a range that can be adequately represented using powers of 10.
What fields use scientific notation?
Mostly the sciences use scientific notation
Do psychologist use scientific notation?
psychologist do not usually use scientific notation
Do physicists use scientific notation?
Yes, physicists use scientific notation
Why do people use powers of 10 for scientific notation not 5 or 12?
That is related to the fact that our numbering system - the decimal system - is based on powers of 10.
How do judges use scientific notation?
Judges usually don't use scientific notation.
