Which is the biggest number? 1. 4 * 10-8 2. 4 * 10-18 3. 3.0 * 10-18 4. 3 * 10-8?

1. 4x10-8

2.4x10-18

3.0x10-18

4.3x10-8

1. You must do

4x10=40 first (according to "B. O. D. M. A. S")

then - 8 which is 32

2. You must do

4x10=40 (again)

then - 18 which is 22

3. You must do

0x10=0

then - 18 which is - 18 (Aka negative 18)

4. You must do

3x10=30

then - 8 which is 22

Lets review what we have:

1. 32

2. 22

3. - 18

4. 22

The biggest would be 1

1. 40-8=32

2. 40-18=22

3. 30-18=12

4. 30-8 = 22

#1 is the largest
