R=(1+0.0997/360)^360)-1
R=0.105*100=10.5%
Loan v
R=(1+0.1016/4)^4)-1
R==0.106*100=10.6%
Loan u is the lower by 0.1%

Answer:

B. 1 + ln 2 - ln x

General Formulas and Concepts:

Algebra II

Natural logarithms ln and Euler's number e
Logarithmic Property [Multiplying]: $\displaystyle log(ab) = log(a) + log(b)$
Logarithmic Property [Dividing]: $\displaystyle log(\frac{a}{b}) = log(a) - log(b)$

Step-by-step explanation:

Step 1: Define

Identify

$\displaystyle ln(\frac{2e}{x})$

Step 2: Simplify

Expand [Logarithmic Property - Dividing]: $\displaystyle ln(\frac{2e}{x}) = ln(2e) - ln(x)$
Expand [Logarithmic Property - Multiplying]: $\displaystyle ln(\frac{2e}{x}) = ln(2) + ln(e) - ln(x)$
Simplify: $\displaystyle ln(\frac{2e}{x}) = ln(2) + 1 - ln(x)$
Rewrite: $\displaystyle ln(\frac{2e}{x}) = 1 + ln(2) - ln(x)$
