The two numbers shown in a scientific notation are decimals and a 10 with a positive or negative exponent.
Example: 2.50 times 10^2= 250
Example2) 2.50 times 10^-4= 0.000250
Hint: if a exponent is a - it will be small, if it is greater than 1 it will be big. 10^0 will be1.
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.
Since the numbers astronomers use are often very large or very small, they frequently use scientific notation to describe sizes and sentences in the universe.
Scientific notation is best used to represent very large or very small numbers, such as numbers with many zeros. It is commonly used in scientific and mathematical calculations, as well as in fields like physics and astronomy where extremely large or small values are often encountered.
5 to the power of 40 is equal to 9,094,947,017,729,280,000. This can be calculated by multiplying 5 by itself 40 times. In mathematical notation, it is written as 5^40. This number is extremely large and is often expressed in scientific notation for easier understanding.
Sometimes engineers use either scientific or engineering notation, although you are correct that most of the time engineering notation is used. The reason for this the use if greek letter prefixes for quantities. Very often large and small quantities are expressed as micro, mega, giga, nano, and so on. These terms relate to engineering notation in multiples of 1000 or 1/1000. It is a very convenient shorthand not only in writing but also while speaking.Read more: Why_in_engineering_you_use_engineering_notation_instead_of_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.

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.
384401 would be expressed as 3.84401X105 However, we would often simply round this down to two decimal places: 3.84X105 . Scientific notation is a very convenient way to express very large or very small numbers.
Since the numbers astronomers use are often very large or very small, they frequently use scientific notation to describe sizes and sentences in the universe.
addresses are 32-bit numbers often expressed as 4 octets in "dotted decimal" notation (for ... Internet Corporation for Assigned Names and Numbers ...
It is because some of the numbers that they deal with are very large or very small.
When adding or subtracting numbers in scientific notation, ensure that the exponents are the same. If the exponents are not the same, adjust one or both numbers to match. Then, add or subtract the coefficients while keeping the exponent the same. Finally, simplify the result if necessary by converting it back to proper scientific notation.
Scientific notation is a way of representing numbers, usually very large or very small, in the form a*10^b where 1
Scientific notation is a way of writing numbers that accommodates values too large or small to be conveniently written in standard decimal notation. Scientific notation has a number of useful properties and is often favored by scientists, mathematicians and engineers, who work with such numbers. In scientific notation all numbers are written like this:a × 10bMost calculators and many computer programs present very large and very small results in scientific notation. Because superscripted exponents like 107 cannot always be conveniently represented on computers, typewriters and calculators, an alternative format is often used: the letter E or e represents times ten raised to the power, thus replacing the x 10n.ExamplesAn electron's mass is about 0.00000000000000000000000000000091093822 kg. In scientific notation, this is written 9.1093822×10−31 kg or 9.1093822E−31The Earth's mass is about 5973600000000000000000000 kg. In scientific notation, this is written 5.9736×1024 kg or 5.9736E24The Earth's circumference is approximately 40000000 m. In scientific notation, this is 4×107 m or 4E7

I do not really know but i heard that scientific notation is often good to learn you can look this up in math books
