To three significant figure, 483.54 becomes 484.
The rule when rounding off numbers is "If the first figure to be discarded is 5 or more then the previous figure is increased by 1".
Expressed in Scientific Notation, 484 becomes 4.84 x 102.
0.2 in standard form is written as ( 2 \times 10^{-1} ). This notation represents the number in a way that highlights its significant figures and the scale of the number relative to powers of ten.
Scientists have developed a shorter method to express very large numbers. This method is called scientific notation. Scientific Notation is based on powers of the base number 10.The number 123,000,000,000 in scientific notation is written as :
In standard form, 0.086 can be expressed as (8.6 \times 10^{-2}). This notation represents the number in a way that highlights its significant figures and scales it using powers of ten. The exponent indicates that the decimal point has been moved two places to the right to convert it into a number between 1 and 10.

by the powers VESTED in me is correct.
Decimal notation is.

There are three rules that are used when rounding to a desired number of significant digits (figures): 1. All digits that are not zero, are significant 2. In a number that does not have a decimal point, all zeros between two non-zero digits are significant digits 3. In a number that has a decimal point, all zeros after the leftmost non-zero digit are significant Examples: 12345 rounded to 3 significant digits: 12300, or 1.23 x 104 12.345 rounded to 3 significant digits: 12.3, or 1.23 x 101 0.012345 rounded to 3 significant digits: 0.0123, or 1.23 x 10-2 0.012045 rounded to 3 significant digits: 0.0120, or 1.20 x 10-2 In the last example the zero after 2 is significant. That is the reason for keeping it in the result when rewriting it in powers of 10 notation.
0.00482 in standard powers-of-ten notation is 4.82 x 10^-3.
when you work with scientific notation you get to use the powers of ten
Using power-of-notation makes it easy to multiply numbers.
