Professor PC Thomas Classes · Answer

(a) : According to the rules of significant figures: In 2.000, trailing zeros after a decimal point are significant, making it 4 significant figures. In 0.020, leading zeros are never significant, but the trailing zero after the nonzero digit is, making it 2 significant figures. In 200.0, the decimal point dictates that all trailing zeros are significant, making it 4 significant figures.
