1) Scientific notation is defined mathematical representation used to to represent the a decimal number which present between 1 to 10 multiplied by 10 raised to power equal ti some integer. For example:

$0.00051 =5.1\times 10^{-4}$

Hence, the correct option is D.

2) The scientific notation of number 0.0000000708.

0.0000000708 = $708\times 10^{-10}=7.08\times 10^{-8}$

Hence,the correct answer is option A.

3)When the power of the number ten is in negative.

if the power is more negative number will be smaller.

If the power is less negative the number will greater.

Greatest number from the given option is $6.1\times 10^{-7}$

$6.1\times 10^{-7}>4.1\times 10^{-7}>5.1\times 10^{-7}>3.1\times 10^{-7}$

4) $\frac{1}{8000}=0.000125$

$\frac{125}{1000000}=1.25\times 10^{-4}$

Hence, the correct answer is option B.
