Question

Aly's science class was looking at bacteria through a microscope. Aly's teacher said some bacteria can be as small as 0.00365 cm long. What is the length of the bacteria written in scientific notation?

Answer 1

Answer:

$0.00365\ cm=3.65\times 10^{-3}\ cm$

Explanation:

Aly's teacher said some bacteria can be as small as 0.00365 cm long.

In this problem, we need to write the length of the bacteria written in scientific notation. Any number can be written in the form of scientific notation as follows :

$N=a\times 10^b$

a is a real no and b is an integer

In the given number, there are two zeroes before 3. We need to shift the decimal after 3. It can be done as follows :

$0.00365\ cm=3.65\times 10^{-3}\ cm$

Hence, this is the required solution.
