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.

the answer is 1/4
