Detailed explanation-1: -Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650, 000, 000 can be written in scientific notation as 6.5 ✕ 10^8.
Detailed explanation-2: -Scientific notation makes it easy to compare numbers that have very different values because all the zeroes have been replaced with the much more readable exponent. Numbers with a greater exponent are always bigger than numbers with a lesser exponent.
Detailed explanation-3: -Scientific notation is simply a way of writing numbers. It is especially useful in expressing very large or very small numbers because it is shorter and more efficient and it shows magnitude very easily. Every real number can be written as a product of two parts: a decimal part times an integer power of ten.
