The form that uses only powers of ten are logarithms to base 10. The scientific notation does use powers of ten but the original number is also used in this representation.
Using power-of-notation makes it easy to multiply numbers.
8.7329 x 10e3
820.681+10
Not quite sure what you mean, do you mean as a form of scientific notation, for example 3,000,000 would be represented as 3x106 (6 zeros)
4,702 = (4 x 103) + (7 x 102) + (0 x 101) + (2 x 100)
scientific notation or standard form
300
Decimal notation is.
scientific :D
Using power-of-notation makes it easy to multiply numbers.
8.7329 x 10e3
582 = 5.82*102
positive powers of ten are standard form, this is when large numbers are simplified to make math easier e.g 100000000 is 1x10^9
The are used to represent numbers using powers of ten.
30,332 in expanded form using powers ten = (3 x 104) + (0 x 103) + (3 x 102) + (3 x 101) + (2 x 100)
Scienctific method
81.402 in expanded form using the powers of ten = (8 x 10^1) + (1 x 10^0) + (4/10^1) + (0/10^2) + (2/10^3)
