Determine the number of significant digits in each number, and write the specific significant digits. a. 1.405000
b. 2.0.0098
c. 3.39.999999
d. 4.13.00
e. 5.80,000,089

1.    405000      significant figures= 3    (405)

2.    0.0098             significant figures= 4   ( after the decimal 0098)

3.    39.999999        significant figures= 8   ( all of them )

4.    13.00                             significant figures= 4     ( all of them )  

5.   80,000,089                  significant figures= 8    ( all of them )

Step-by-step explanation:

1.    405000      significant figures= 3    (405)

2.    0.0098             significant figures= 4   ( after the decimal 0098)

3.    39.999999        significant figures= 8   ( all of them )

4.    13.00                             significant figures= 4     ( all of them )  

5.   80,000,089                  significant figures= 8    ( all of them )

Here are the rules for determining the significant figures.

1) Numbers that are after the zero decimal are significant.

2) Non zero numbers before or after the decimal containing whether a zero or not are significant numbers

3) Zero numbers that are at the end are not significant numbers.

4) Zero after the decimal in significant figures is significant.
