b.
6.31 × 10- 8
c.
8.61 × 10- 8

Solution:

Order the exponents.

- 8 < - 7 < - 6
So, 10- 8 < 10- 7 < 10- 6.

Compare numbers with the same exponent.

6.31 < 8.61
So, 6.31 × 10- 8 < 8.61 × 10- 8 < 6.31 ×10- 7 < 3.07 × 10- 6.

Therefore, the smallest number is 6.31 × 10- 8.

c.
3.61 × 10-4
d.
1.04 × 10-2


Solution:

Order the exponents.

- 4 < - 3 < - 2
So, 10-4 < 10-3 < 10-2.

Compare numbers with the same exponent.

2.31 < 3.61
So, 3.61 × 10-4 < 2.31 × 10-3 < 3.61 × 10-3 < 1.04 × 10-2.

Therefore, the smallest number is 3.61 × 10-4.

Which among the following numbers is the largest?
a.
5.81 × 10-7
b.
4.71 × 10-7
c.
3.71 × 10-6
d.
6.21 × 10-8


Solution:

Order the exponents.

- 6 > - 7 > - 8
So, 10- 6 > 10- 7 > 10- 8.

Compare numbers with the same exponent.

5.81 > 4.71
So, 3.71 × 10-6 > 5.81 × 10-7 > 4.71 × 10-7 > 6.21 × 10-8.

Therefore, the largest number is 3.71 × 10-6.


Correct answer : (3)
 39.  
Choose the smallest number.
a.
5.33 × 108
b.
6.33 × 108
c.
9.35 × 107
d.
5.33 × 109


Solution:

Order the exponents.

7 < 8 < 9
So, 107 < 108 < 109.

Compare numbers with the same exponent.

5.33 < 6.33
So, 9.35 × 107 < 5.33 × 108 < 6.33 × 108 < 5.33 × 109.

Therefore, the smallest number is 9.35 × 107.

a.
9.21 × 104
b.
9.81 × 103
c.
9.61 × 102
d.
9.41 × 104


Solution:

Order the exponents.

4 > 3 > 2
So, 104 > 103 > 102.

Compare numbers with the same exponent.

9.41 > 9.21
So, 9.41 × 104 > 9.21 × 104 > 9.81 × 103 > 9.61 × 102.

Therefore, the largest number is 9.41 × 104.
