Question

A human red blood cell is about 0.00000 8 in diameter. Put this number in scientific notation.​

Answer 1

Answer:

$\large\boxed{0.000008=8\cdot10^{-6}}$

Step-by-step explanation:

The scientific notation:

$a\cdot10^k$

where 1 ≤ a < 10 and k ∈ Z.

0.000008

You must move the comma 6 places to the right.

$0\underbrace{.000008}_{6\rightarrow}=8\cdot10^{-6}$

$0.000008=\dfrac{8}{1,000,000}=8\cdot10^{-6}$
