Ecole Supérieure de Commerce de Neuchâtel Pierre Marchal 2017 Attribute to: Kenny M. Felder (Rice University)
2
Objectives of the course
By the end of the course, you should be able to: Solve using the exponents Solve by changing one exponent Solve using the logarithm Solve equation with exponents or logarithms
3
1. Exponents have the same base
If match Transpose equation on the number Solve the Example: Solve the equation We have: bases exponents corresponding equation
4
2. Exponents with different bases
May need to change one number So they can Example: Solve the equation We have: equation is now exponent match case 1
5
3. Solving using logarithms
When it is to match the bases Take the of both sides of equal sign Then apply the Example: Solve the equation By taking the log, we have: We apply the properties of logarithms: not possible logarithm properties of the logarithms
