Answer
Answer:
a. 6 b. 3 c. 3 d. 2
Explanation:
Step1: Rule for non - zero digits
Non - zero digits are always significant. In 187.032, all 6 digits (1, 8, 7, 0, 3, 2) are significant.
Step2: Rule for leading zeros
Leading zeros (zeros before non - zero digits) are not significant. In 0.0601, only 6, 0, 1 are significant, so 3 significant digits.
Step3: Rule for scientific notation
In scientific notation (a\times10^{n}), the digits in (a) are significant. In (1.30\times 10^{- 12}), 1, 3, 0 are significant, so 3 significant digits.
Step4: Rule for trailing zeros without decimal
Trailing zeros in a number without a decimal point may or may not be significant. In 620, assuming no other context, only 6 and 2 are significant, so 2 significant digits.
