80000

Step-by-step explanation:

Significant figures are any number but zeroes.

However, in some cases, zeroes also count as significant figures.

Zeroes are significant figures when between other non-zero numbers.Zeroes are significant when you see a dot on the right indicating that zero is not a place holder.They are not significant when serving as place holders, such as zeroes on the right side of a number. For example, .004 has 1 sig fig. The 2 zeroes on the left aren't sig figs because they're just place holders.Zeroes on the right side of a decimal are also significant.
