Answer 1

The scientific notation : A. 9.594 x 10⁻³

Further explanation

Scientific Notation consists of 2 parts  

1. the first part: the first digit followed by the decimal point  

2. The second part: the power of 10 (the exponents).which shows the number of digits after the decimal point

Multiply scientific notation :

1. multiply coefficients

2. add the exponents.

3. converted to scientific notation.

3.120 x 10⁻⁷ x 3.075 x 10⁴ =

• multiply coefficients

$\tt 3.120\times 3.075=9.594$

• add the exponents.

$\tt 10^{-7}\times 10^4=10^{-7+4}=10^{-3}$

• combine

$\tt 9.594\times 10^{-3}$
