Unformatted text preview: Solve for x : 20 9 2 = +x x e e . Example 5: Solve for x : 3 2 = +x e An equation in which the logarithm of the variable occurs is called a logarithmic equation. To solve such an equation, isolate the logarithmic expression on one side of the equation. Then write the equation in exponential form and solve for the variable, or use the law of logarithms to simplify and solve fore the variable. Example 6: Solve for x : 2 ) 4 ( log 3 =x Example 7: Solve for x : ) 12 ( log ) 5 2 ( log 8 8 = + x Example 8: Solve for x : ) 2 ( log ) 1 ( log log 6 6 6 = + + x x Example 9: Solve for x : 2 ) 5 ( log log 6 6 = + + x x Example 10: Solve for x : ( 29 2 4 ln 2 = + x...
