Question

Help guys please ....

Answer 1

0.000008 m

Explanation:

The diameter of a red blood cell is
`8* 10^(-6)\ m`. We need to write the value in the standard notation.

`10^(-6)` means there are 5 zeros before 8. It can be written as :

`8* 10^(-6)=(8)/(10^6)\ (\because x^(-a)=(1)/(x^a))\\\\=(8)/(1000000)\\\\=0.000008`

So, the standard notation is 0.000008 m. Hence, the correct option is (d).
