Some simple logarithm questions
the book simply says find the exact value of each expression. without a calculator. using properties of logarithms.( which it lists, but I can't see where they apply)
for this I just divided 18 by 3 getting 6. log6^6=1? is that right?
2.log3^8 * log8^9
for this i tried change of base. I did
(logb^8/logb^3) * (logb^9/logb^8)
I'm completely lost on this one. Supposedly these are all really easy to do without a calculator. i just don't know how to do them. Any help would be greatly appreciated.
