Homework Help: precalc help

Posted by Rebekah on Wednesday, November 21, 2012 at 6:32am.

Find the exact value without a calc

1. log base 3 of 8 times log base 8 of 9. I started by changing both bases to 10 but dont know what to do from there.

2. e ^ log base e^2^9. I hope that isnt confusing. My teacher said we are suppose to get the bases all e, but how because there is only 1 log.

Suppose that ln 2= a and ln 3= b. Use the properties of logs to write each in terms of a and b

1. ln .5

thanks
