Why is it important to multiply and divide numbers in scientific notation?

This can be important when a measurement of importance is the small difference between two very similar quantities. If the similar quantities are expressed in scientific notation such that some decimals are lost, it is possible that the difference appears to be zero.

That's why. Scientific notation makes the multiplication and division of large number, especially by hand, much, much easier.
2.3 X 1011 * 3.5 X 108
= 8.05 X 1019
============Multiply bases and add exponents ( watch ending decimal places as the exponent may have to change ). In division you divide top base by bottom and subtract bottom exponent from top exponent.

How do scientists use scientific notation?
Scientists use scientific notation to compute very large or very small numbers.
Is exponential notation the same as scientific notation?
No. 35 is exponential notation, (3 is the base of the exponent 5), but in scientific notation the base must be 10 and the exponent must be an integer. 100.1 is exponential notation but not sci. notation.
How do pharmaceuticals use scientific notation?
Pharmaceuticals use scientific notation to compute very large or very small numbers.
Scientific notation is a way of making numbers scientific true or false?
You don't - just as you don't with a number in normal notation.
How do you write 46322 in scientific notation?
Such small numbers aren't normally expressed in scientific notation but it is: 4.6332*104
When subtracting numbers in scientific notation what you do with exponents?
yes its really important
What is the importance of scientific notation?
it is important to us to use scientific notation because if we use it we can read the numbers easily. Scientific notation is important because it make writing numbers easier. For example, you are contestant in a quiz bee and the examiner says,134000000000000x500000000000 or something like that you will lost time writing zeroes and you will also confused about it instead we can just write it in a scientific notation.
Is scientific numbers and scientific notation the same?
No. Scientific numbers are constants that appear in science. They may or may not require scientific notation.
Why is it important to have a method of denoting numbers that are very small or very large with a minimal amount of writing?
Scientific notation makes it easy to write down numbes, and to compare them (if normalized scientific notation is used). It is also fairly easy to multiply and divide them, once you know what you are doing.
Why is the use of scientific notation important in chemistry?
it is a way of writing numbers large or small and it is important in math
Why is it important the scientific notation in chemistry?
Because sometimes numbers get very big or very small.
What is the disadvantage of using scientific notation?
If you are adding or subtracting two numbers in scientific notation, you must rewrite one of the numbers to the same power of ten as the other, before performing the addition (or subtraction).
What are 2 ways of writing numbers?
standard notation and scientific notation For example: 126,000 is standard notation. 1.26X105 is scientific notation.
Express a numbers of scientific notation?
how to express scientific notation to a simle number
What requires scientific notation?
Scientific notation is required for very large or very small numbers.
What is the express numbers in 0.00000029384 in scientific notation?
It is: 2.9384*10^-7 in scientific notation
How does scientific notation differ from ordinary notations?
Ordinary notation is where the numbers are laid, or written out. Scientific notation is a short handed version with numbers that indicate the amount of zeroes behind the end of the numbers.
