व्याख्या
According to the rules for significant figures: (1) Leading zeros (zeros to the left of the first non-zero digit) in a number less than \( 1 \) are not significant. Therefore, the first three zeros in \( 0.003050 \) are not significant. (2) Zeros between non-zero digits are significant. (3) Trailing zeros to the right of the decimal point are significant. Thus, the digits \( 3, 0, 5, \) and the final \( 0 \) are significant, giving a total of \( 4 \) significant figures.
