$\log_2 \frac{80}{9}-2 \left(\log_2\frac{16}{15} \right) + \frac{3}{2} \log_2 \frac{5}{2}$

I think you forgot to paranthesize the right terms
in this particular problem we would have to use properties of logarithms, so, log(a^b)=blog(a) and log(axb)=loga+logb, similarly log(a/b)=loga-logb
**When helping people, please do not dump the full solution. **
Remember that these people are trying to learn concepts, and our goal should be to reinforce them. Giving them a solution will not help.
**Instead, give them hints and guide them toward the correct solution. **
You can ask things like "what part did you get stuck on?" or "what have you tried so far?" or give them a small starting hint. This ensures better learning. For more tips, reach out to Schlaumau (@schlaumau).
what would be your first step?
@frank kraken
wha5 r u trying to get then
$\log_2 \frac{80}{9}-2 \left(\log_2\frac{16}{15}+ \frac{3}{2} \log_2 \frac{5}{2} \right)$
this?
wolfqz
this or does the bracket end before log_2 5/2
dose not matter i think because the -2 will go with 3/2 * -2 it will be -3
it does matter
in the original question its like this
ye
so first distribute the 2
ok
umm where are you?
wolfqz
use the rule]
A brief description and guide on how to use me was sent to your DMs!
Please use ,list to see a list of all my commands, and ,help cmd to get detailed help on a command!
