Very large and very small numbers are expressed in scientific notation
Scientific notation or standard form
A useful way of writing large or small numbers instead of having to write alot of zeros. Example- 5,000= 5 x 1,000= 10 to the 3rd power :)
The main reason for using scientific notation is to express extremely large or small numbers more conveniently. It allows us to represent these numbers in a concise and standardized way, by using a power of 10. This makes it easier to communicate and work with very large or small values in various scientific and mathematical fields.
It can simplify writing very large numbers. For example, a googol, which is 10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 (and there may be a mistake there!) can be written ever so simply as 1*10^100.A googol maybe a curiosity but there are physical constants such as Avogadro's number which is 6.022140857*10^23, or a light year, which is 9.4607*10^15 metres where it is easy to make a mistake in the number of zeros..
Multiply all terms by a number (usually a power of 10) large enough to turn all decimal numbers into whole numbers. For example, take .4x = .75x - 2; multiply everything by 100 (102) to get 40x = 75x - 200. Obviously, this method won't work with irrational decimals such as pi.

Scientific notation is a way to represent very large or very small numbers in a concise and standardized format. It involves writing a number as the product of a decimal number between 1 and 10 and a power of 10. This format is particularly useful when working with numbers that have many zeros.

Usually not.
1.5E14 is the calculator/computer method of writing scientific format numbers The E stands for Exponent and means "×10 to the power) → 1.3E14 = 1.3 × 10¹⁴ = 130,000,000,000,000
A billion is one thousand million. It can be written109.This method of writing numbers is called scientific notation.A billion to the power of 10 is a billion multiplied by itself 10 times1090
The most used method was the regulation of big businesses. This was because there was a large concern that too much of the economic power resided in the hands of the financial elite.
This number is too big for writing in scientific notation, or even power towers; it can be defined recursively (see the definition in the Wikipedia, for example), or approximated with special systems, more appropriate for very large numbers, such as the Conway Arrow Notation.
