That would be .1+.03+.005+.0007

Do you mean 1.9 x 10^4 ?
70 = (7 x 101) + (0 x 100)
7 ten thousandths in standard form is written as 0.0007.
That would be .1+.03+.005+.0007
81.8887 = 80 + 1 + 0.8 + 0.08 + 0.008 + 0007 ( in expanded decimal form)
300
2x10^6
8.7329 x 10e3
10+8+40/10
30,332 in expanded form using powers ten = (3 x 104) + (0 x 103) + (3 x 102) + (3 x 101) + (2 x 100)
6000 + 100 + 20 + 5
.0007
Because the basis for expansion are the powers of ten - exactly the same as in the standard form.
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)
Do you mean 1.9 x 10^4 ?
