0.000 000 000 001, or 1 x 10-12 in scientific notation.
001 equals 1 so it is just 1 * 10^0 (or 1e0 if you want). If you meant to type 0.01, then it would be 1 * 10^-2 (or 1e-2).
The standard notation for 6.256 x 10-001 = 0.6256

Significant figures is a way of trying to convey how accurately something is being measured. A very accurate scale may measure .001 grams, a bathroom scale may be only accurate to within 2 lbs. Exponential notation has nothing to do with measurement. It is just a choice on how to write a number, usually for some mathematical application. 243 = 35 this is exponential 'notation'. Scientific notation is a certain type of exponential notation in which the base must be 10. 243 = 2.43 x 102 that is scientific notation.
depends, you want it before or after the decimal point? before= 001 after= .001
15 000 894 written with 5 significant figures is 15 001 000, as the 894 rounds up to the nearest significant figure. 1.5001*10^7
