Respuesta :
2.0x10^-5 or 2.0E-5 —this is because as a small decimal number, you move the decimal to the right five spaces and then add a negative to the decimal to indicate that when you translate back (from scientific notation to 0.00002) you will move the decimal to the left
Answer:
[tex]2\times10^{-5}[/tex].
Step-by-step explanation:
We have been given that an egg of a certain kind of insect called a Tachinidae is 0.00002 meters long. We are asked to write the length in scientific notation.
To write a number in scientific, we need to factors. One factor is between 0 and 10 and second is a power of 10.
The first factor will be 2.
Since our given number has 5 digits after decimal, so we will multiply 2 by 1 divided by 10 to the fifth power.
[tex]0.00002=2\times\frac{1}{10^5}[/tex]
Using exponent property [tex]\frac{1}{a^m}=a^{-m}[/tex], we can write our expression as:
[tex]0.00002=2\times10^{-5}[/tex]
Therefore, the length in scientific notation would be [tex]2\times10^{-5}[/tex].
