Question

question 23 (1 point) listen how many significant figures are in 0.006570? a) 3 b) 4 c) 5 d) 6 e) 7

Explanation:

Step1: Identify leading zeros

Leading zeros (before non-zero digits) are not significant. In 0.006570, the first three digits (0,0,0) are leading zeros and do not count.

Step2: Count non-zero & trailing zeros

Non-zero digits (6,5,7) are significant. The trailing zero after 7 is after a decimal point, so it is significant. Count: 6,5,7,0 → 4 total.

b) 4
