Exponential and Logarithmic Equations and Inequalities A logarithmic equation is an equation with a

Exponential and Logarithmic Equations and Inequalities A logarithmic equation is an equation with a logarithmic expression that contains a variable. There are two kinds of logarithmic equations: • Equations with logarithms on both sides of the equal sign. • Equations with logarithms only on one side. (exponentiate the equation) Check answer to make sure it does not give a log(x < 0). Holt Mc. Dougal Algebra 2

Exponential and Logarithmic Equations and Inequalities Economics Application 10. The moment magnitude M of

Exponential and Logarithmic Equations and Inequalities Economics Application 10. The moment magnitude M of an earthquake that releases energy E (in ergs) can be modeled by this equation: On October 9, 1984, the largest earthquake in Georgia occurred in Dalton with a magnitude of 4. 2. How much energy did this earthquake release? 4. 2 = 0. 219 ln E +1. 17 Substitute 4. 2 for M. Solve for E. The earthquake released about 1, 020, 309 ergs of energy. Holt Mc. Dougal Algebra 2
