Integers ending in 0 are an ambiguous case. I would say 2 significant figures, but if it appeared alongside a list of numbers such as 1710, 1690, 1750, then I would have to say 3 sig figs and if it was with 1705, 1696, 1729 then 4 sig figs.

8.0 x 10^3
The number whose farthest right significant digit determines it. Whatever place that digit is in is the last significant digit in the sum. For example: 433 + 150 + 3.67 + 8000 = 8586.67, but in sig figs this is only 9000, as the thousands digit is the lowest digit that can be represented.
