Use natural lograithms to solve each equation. Round answers to the nearest hundreth.
I am stuck here. Could anybody usher me along?
2. Change of base rule:
Take logs again, this time I will pick base 4 to demonstrate the change of base rule:
However if your calculator does not give you option to use base 4 then use the change of base rule above. In this case a = 4, b = ln(10) and c = 10
edit: using base e or 10 instead of base 4 would be easier, I just wanted to demonstrate the change of base rule
