Question

question 4
how many significant figures are in the following number? 0.000710
○ 7
○ 6
○ 2
○ 3

Explanation:

Step1: Recall significant figure rules

Leading zeros (before non - zero digits) are not significant. Trailing zeros after a decimal point and after non - zero digits are significant. Non - zero digits are always significant.

Step2: Analyze the number 0.000710

• The leading zeros (the four zeros before 7) are not significant.
• The non - zero digits 7 and 1 are significant.
• The trailing zero after 1 (the zero at the end of 0.000710) is significant because it is after the decimal point and after non - zero digits.
• So, the significant figures are 7, 1, and 0. That's a total of 3 significant figures.
