Question

$\left( \frac{a - b}{a} \right) + \frac{1}{2}\left( \frac{a - b}{a} \right)^{2} + \frac{1}{3}\left( \frac{a - b}{a} \right)^{3} + ..... =$

• A. $\log_{e}(a - b)$
• B. $\log_{e}\left( \frac{a}{b} \right)$
• C. $\log_{e}\left( \frac{b}{a} \right)$
• D. $e^{\left( \frac{a - b}{a} \right)}$

Answer 1

Answer: (B)

$\log_{e}\left( \frac{a}{b} \right)$

Answer 2

$\log_{e}(1 + y)$

$\frac{e^{5x} + e^{x}}{e^{3x}}$.
