How do you convert a number from standard to scientific notation? - Answers

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:9.8743Then, count how many places you moved the decimal.In this case, it was 6.So, you have to multiply the number by 10-6So this number in scientific notation would be:9.8743 × 10-6This is also sometimes written (how most calculators display it):9.8743e-6If you have a large number, say like345,938,200,000,000,000,000you do the same thing.So this would become:3.459382e20 or 3.459382 × 1020
