Natural Logarithmic And Exponential Functions Logarithmic Equation
04/01/18
When evaluating exponential equations using logarithms, why do we need to isolate the variable first?
For example,
3e^(2x)=1821
The correct solution would be,
1. Divide 3 on each side, thus e^(2x)=607
2. Take the natural log on both sides: lne^(2x)=ln607
3. Eliminate...
