Step-by-step explanation:

Consider 0.0000004

0.0000004=

10000000

4

=

10

7

4

0.0000004=4×10

−7

Therefore the size of the bacteria is 4×10 ratio to 7

Answer 2

Answer:

4*10^-8

Step-by-step explanation:

1.This is a number smaller than 0, so we will need to shift the decimal point right

2.We write the decimal point after the first non-zero number, followed by the rest of the non-zero digits: 4. This is the base.

3.Next we count how many decimal places we shifted the decimal point

4. Next, we count how many zeroes are in the decimal. There are 8 zeroes so the base will be negative because the number is smaller than 0.
