Answer:

Scientific notation is just a short hand way of expressing gigantic numbers like 1,300,000 or incredibly small numbers like 0.0000000000045. Also known as exponential form, scientific notation has been one of the oldest mathematical approaches. It is favored by many practicioners. If numbers are too big or too small to be simply calculated, people reffer to scientific notation to handle these circumstances. This method is used by engineers, mathematicians, scientists.

An example of scientific notation is 1.3 ×106 which is just a different way of expressing the standard notation of the number 1,300,000. Standard notation is the normal way of writing numbers.

Step-by-step explanation:

this is the integer or first digit in any Scientific Notation. For example in 1.3 ×106, the mantissa is the "1"
