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)

Decimal notation is.
The number 98.704 in expanded form using powers of ten is expressed as (9 \times 10^1 + 8 \times 10^0 + 7 \times 10^{-1} + 0 \times 10^{-2} + 4 \times 10^{-3}). This breaks down each digit according to its place value, with the whole numbers represented by positive powers of ten and the decimal digits by negative powers of ten.
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)
