Scientific notation is often used to represent very large and very small numbers. Actually, you can also express a "normal-sized" number in scientific notation. So, whenever there is a number, you may use scientific notation.
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 :
It is appropriate to use scientific notation when dealing with very large or very small numbers, particularly when the numbers have many zeroes. Scientific notation is a more compact and efficient way to express these numbers, making calculations and comparisons easier. Additionally, scientific notation is commonly used in scientific fields to express measurements and mathematical equations.
Sometimes. Scientific notation is used to express very small or very large numbers. If the problem does not involve any such numbers then there is no need for scientific notation.
