A large number like this would be rounded to 30,000,000,000 and then expressed in scientific notation as: 3.0*1010
In general, you cannot. If the number in scientific notation has not been rounded then express it is normal form and proceed from there.
862,400 in scientific notation rounded to three significant digits is 8.63 x 10^5
7.0 x 109 (approximate, roughly estimated, rounded)
5.91352 x 10^9 (but generally it is rounded to 5.91)
Standard notation is just a term that means what everyone does all the time. For example... Scientific notation: 3.0x-10^3 (also 3.0e-3) Standard notation: 0.003 Rounding is likewise no different than what you would do with any presentation... round to the appropriate digit. For example, if we rounded to the third digit.... Scientific: 3.7x-10^3 => 4.0x-10^3 Standard notation: 0.0037 => 0.004
