What are the advantages of using scientific notation to express very large and very small numbers?
Scientific notation lets us express a large or a small number without having to write a lot of zeros before or after it. Try writing out 3 x 10^9000 without scientific notation.
What is the meaning of exponential notation?
The exponential notation consists in writing a number as a value comprised between 0 and 10 and a power of ten. For example 1900 -> 1.9 . 103 0.00023 -> 2.3 . 10-4 It is very useful both to represent very big or small numbers (for example the Avogadro number is about 6.2 . 1023, a n umber that would have 23 digits in normal notation) and to understand the order of magnitude of a number, without taking into account its exact value. Several times in science an approximate evaluation is needed to understand what is the dimension of something, without evaluating its exact value. In this case calculations can be directly done with exponents rendering them direct and simple.
Why do you use scientific notation to write numbers?
Scientific notation is used to express numbers that are very large or very small in a compact and standardized way. It consists of a number between 1 and 10 multiplied by a power of 10. This notation helps to simplify calculations and make comparisons between numbers easier. It also allows for expressing extremely large or small values without having to write out all the zeros.
What is a short way of representing very large and very small numbers without all of the place-holding zeros?
You can use Scientific Notation which represents the number as an exponential using powers of 10.For example:0.0001 = 1x10-4 or just 10-40.00000342 = 3.42x10-61000000 = 1x106 or just 106342000000 = 3.42x108
What are the example of scientific notation?
Scientific notation is a way to signify really long numbers without writing it out in full, all 50 digits. 1,000,000,000 in scientific notation is 1.00 X 109
