The Richter scale provides a measure of the magnitude of an earthquake. The following formula shows a relationship between the amount of energy released and the Richter number. \[ \mathrm{M}=\frac{2}{3} \log \frac{\mathrm{E}}{0.007} \] where \( \mathrm{E} \) is measured in kilowatt-hours. a. What value of \( E \) gives a Richter number \( M=8.1 ? \) (Use scientific notation. Use the multiplication symbol in the math palette as needed. Round to three decimal places as needed.)
