Answer 1

Answer:

1

Explanation:

because the rule in decimal states that we count significant figures from the first non-Zero number to the end so in 2.0 the first non-zero is 2 and till the end means 2 significant figures

but it there is a different law for non-decimal numbers in non-decimal numbers we count significant figures from 1st non-zero number to the last non-zero number so in 2000 there is only 1 significant figure
