3

Explanation:

Step1: Recall significant - figure rules for 0.1000

Non - zero digits are always significant. Leading zeros (zeros before non - zero digits) are not significant. Trailing zeros after a decimal point are significant. In 0.1000, the non - zero digit 1 and the three trailing zeros after the decimal point are significant, so there are 4 significant figures.

Step2: Recall significant - figure rules for 300

When there is no decimal point, trailing zeros may or may not be significant. By default, in 300, we assume there is 1 significant figure (the 3). To indicate 2 or 3 significant figures, we would write 3.0×10² or 3.00×10² respectively.
