Decimal notation is.
Expanded Notation of 80 = (8 x 101) + (0 x 100).
28/42
It is 59/1000.
they express the numbers using scientific notation
Expanded Notation of 456 = (4 x 102) + (5 x 101) + (6 x 100)
To write 387 in standard notation, you simply write the number as it is: 387. Standard notation is the usual way we write numbers using digits, with each digit representing a different place value. In the number 387, the 3 is in the hundreds place, the 8 is in the tens place, and the 7 is in the ones place.
50 : 45 = 10/9
Using scientific notation reduces the need to write out very large or very small numbers as the following examples show:- 1,000,000,000,000 = 1.0*1012 in scientific notation 0.0000000001 = 1.0*10-10 in scientific notation
(4 * 103) + (7 * 102) + (6 * 101) + (8 * 100).
Scientific notation doesn't stop at a centillion. 1 centillion in scientific notation is 1 * 10303, but you can also write 1 * 10304 or even 9 * 109999999 in scientific notation. There is no upper limit to the numbers you can write in scientific notation.
In today's notation: MCCXL
Expanded Notation of 2784 = (2 x 103) + (7 x 102) + (8 x 101) + (4 x 100).
