Use sigma notation to write the following left Riemann sum. Then, evaluate the left Riemann sum using a calculator. \[ f(x)=e^{x} \text { on }[0, \ln 2] \text { with } n=25 \] Write the left Riemann sum using sigma notation. Choose the correct choice below. A. \( \sum_{k=1}^{25} e^{(k-1)\left(\frac{\ln 2}{25}\right)} \cdot \frac{\ln 2}{25} \) B. \( \sum_{k=1}^{25} e^{x} \cdot \frac{\ln 2}{25} \) C. \( \sum_{k=1}^{25} e^{\left(k-\frac{1}{2}\right)\left(\frac{\ln 2}{25}\right)} \cdot \frac{\ln 2}{25} \) The left Riemann sum is (Type an integer or decimal rounded to three decimal places as needed.)
