Answer:
Lets take the number, say .0000098743, for example.
Scientific notation is a number in the form of one digit before the decimal place, multiplied by a factor of 10.
So first off, move the decimal so that there is one digit in front of it (1-9), like so:
9.8743
Then, count how many places you moved the decimal.
In this case, it was 6.
So, you have to multiply the number by 10-6
So this number in scientific notation would be:
9.8743 × 10-6
This is also sometimes written (how most calculators display it):
9.8743e-6
If you have a large number, say like
345,938,200,000,000,000,000
you do the same thing.
So this would become:
3.459382e20 or 3.459382 × 1020
