Answer 2

Answer: $5.42*10^{2}$

Step-by-step explanation:

To solve this problem you must apply the proccedure shown below:

1. Divide 9.756 by 1.8.

2. According the properties of exponents, if you have a division of two powers with equal base, you must subtract  the exponents.

3. Therefore, you obtain the following result:

$\frac{(9.756*10^{-7})}{(1.8*10^{-9})}=5.42*10^{-7-(-9)}=5.42*10^{(-7+9)}=5.42*10^{2}$
