Thank you. I have another log question. Cannot use calculator. So, should I add or subtract first? if I add I get which I can't figure out how to simplify any further. If I subtract , what would I do next? Thanks for helping.
Ah, ok I figured it out.
more log questions: so far I've done: Stuck here. Other problems... thanks!~

Other problems... thanks!~ To help you sufficiently I must know what you have done so far and where you have difficulties doing these questions. Please show your work.

[quote=desiderius1;493586]more log questions: so far I've done: Stuck here. Other problems... Log B2 {logB4 (2) +logB4(8) }^3 Work inside brackets first !/2 +logB4(16/2)=1/2 +2 -1/2 = 2 2^3=8 Now you have logB2(8)=3 bjh
