Hello sorry to post another so soon. This book is VERY hard to learn from... its not very good at explaining. The question says: Evaluate the following logarithm: 10log1019. It never showed me how to do it when theres a number in front of the log. What I got from the log 1019 is log19/log10=1.27875. Now do I multiply this by 10 since thats the number infront.. I have no clue!!! THNX AGAIN!
