Solution

Verified
Step 1
1 of 3

First, Let's review the rules for significant figures:

1- All non-zero numbers are $\textcolor{#418159}{ \textbf{significant} }$ .

2-Zeros between two non-zero digits are $\textcolor{#418159}{ \textbf{significant} }$.

3- Leading zeros (a zero digit that comes before the first nonzero digit in a number string in positional notation) are $\textcolor{#B54E3A}{ \textbf{NOT significant} }$

4- Trailing zeros in a whole number with decimal are shown are $\textcolor{#418159}{ \textbf{significant} }$.

5- Trailing zeros in a whole number with no decimal shown are $\textcolor{#B54E3A}{ \textbf{NOT significant} }$.

6-Trailing zeros to the right of the decimal are $\textcolor{#418159}{ \textbf{significant} }$.

7- For a number in scientific notation: $m \times 10^{n}$, all digits comprising m are $\textcolor{#418159}{ \textbf{significant} }$ by the first 6 rules; "10" and "n" are $\textcolor{#B54E3A}{ \textbf{NOT significant} }$.
