Question

Which of the following digits are not considered significant?

a.
all nonzero digits
b.
zeroes between nonzero digits
c.
trailing zeroes to the right of the decimal point
d.
leading zeros to the left of the first nonzero digit

Answer 1

If this is talking about significant figures, then I believe D is the correct answer

Answer 2

leading zeros to the left of the first nonzero digit are not considered significant

Explanation:

In order to find the significant digit, we use below rules:

• All non zero digits are considered to be significant.
• If a zero is in between of two digits then it is significant digit.
• All trailing zeros in a decimal point is significant. For example in the decimal number 0.1700, the zeros are significant.
• Leading zeros are not significant. For example in the number 0.0052, zeros are not significant.

Therefore, d is the correct option.

leading zeros to the left of the first nonzero digit are not considered significant
