Do you mean 1.9 x 10^4 ?
820.681+10
70 = (7 x 101) + (0 x 100)
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)
300
not exactly sure what you're asking but 98364 = 9.8364 x 10^4
(3 x 100) + (2/10^1) + (9/10^2)
2x10^6
587 = (5 x 102) + (8 x 101) + (7 x 100)
8.7329 x 10e3
573 = (5 x 102) + (7 x 101) + (3 x 100)
