Answer:
C = 0.40, D = -18
Explanation:
We have the following expression.
[tex]\frac{2.0 \times 10^{-25}}{5.0 \times 10^{-7}} = \frac{2.0}{5.0} .\frac{10^{-25}}{10^{-7}}[/tex]
We apply the Quotient of Powers Property. This property states that to divide powers having the same base, we have to subtract the exponents.
[tex]\frac{2.0}{5.0} .\frac{10^{-25}}{10^{-7}}=0.40\times 10^{-25-(-7)} =0.40\times 10^{-25+7}=0.40\times 10^{-18}[/tex]
Comparing this result to [tex]C \times 10^{D}[/tex], we can deduct that C = 0.40 and D = -18.
