Question 843539
Scientific notation you need the number to be greater than or equal to 1 and less than 10 and a power of 10.
So in this case your number is 5.8740.
Then the exponent of the power of 10 is the number of places you moved the decimal point to get from 58740 to get to 5.8740, in your case 4. 
So then
{{{58740=5.8740*10^4}}}
