LESSON 6:EQUATIONS INVOLVING LOGARITHMS

=Introduction= In your previous Lesson, you discussed the concept of logarithms and the laws of logarithms. You are now going to relate the knowledge acquired to solve equations involving logarithms. In effect you are going to apply the laws of logarithms in solving equations involving logarithms

Lesson Content
Let us consider an equation like 5x=10 Apply the third law of log to make x the subject of the equation. Take log of both sides. log5x=log10 xlog5=log10 x=log10/log5 x=1/0.6990
