Question

A scientist uses an electron microscope to look at tiny structures called stereocillia, which sits in top of hair cells. The diameter of one sterocillium is found to be approximately 2.5 meters. What is the diameter expressed in a scientific notion

Answer 1

2.5*10^0

Explanation:

To write a number in scientific notation or standard form we write the number and multiply it by 10 to the power of any number

The proper format for scientific notation is a x 10^b and it is read "a times 10 to the power of b"

Given the diameter of 2.5

in standard form or scientific notation is
`2.5*10^0`
