Question 261396
Scientific notation is always in the form
{{{6.8273 * 10^(-14)}}} (you can substitute any numbers you like)
Notice there is only 1 digit to the left of the decimal point.
The exponent can be positive or negative
I'll convert your number in steps
{{{.002556 = .02556 * 10^(-1)}}}
{{{.02556 * 10^(-1) = .2556 * 10^(-2)}}}
{{{.2556 * 10^(-2) = 2.556 * 10^(-3)}}} answer
This is the same as {{{2.556/1000}}} and
{{{2.556/1000 = .002556}}}
