Follow up on Warm Up Solve using ln and exponential rules Solve using the intersection on the calc
Proofs of ln and log properties Pick any two numbers M and N. Show that: This goes back to the old exponential properties. When multiplying same base – add exponents When dividing same base – subtract exponents
How do we expand log and ln? Example: Expand More examples…..
Kinshasa is the capital of what African country? The Democratic Republic of the Congo
Prove Exponent Multiplicative Property Show with numbers – choose a number for M and k. This is also a repeat of the exponent property When you raise a power to a power you multiply Examples….
CFU What is the capital of Wisconsin? Who wrote the constitution? Who was the 4 th President of the US?
Equation Solving Two ways to solve equations Take the ln or log of both sides then solve Rewrite as an ln or log then solve First we need to review the change of base property Solve each of these:
