What is standard scientific notation?

Answer 1

Standard scientific notation is just a way of writing very huge or tiny numbers conveniently. One simply uses 10 to the power of n to a large or tiny number to save writing the many zeroes. For example, if you were to write one million in numerals, it would be very taxing to write 1000000. Instead you can write, 10 to the power of six.

Do take note that, when using scientific notation, the actual number should be no smaller than 1 or bigger than 10.

In the case of numbers not as "nice" as a million, say 30402749502, first round it to three significant figures, then write the 10 power n part behind. In this number, the scientific notation should be 3.04 times 10 to the power of 10.

And that's how you do it.
