Rewrite ln12 in terms of ln2, ln3, and ln5. I know ln12 = ln2 + ln2 + ln3 but I'm not sure where the ln5 comes into play. Please help

[Beezohh]

You're Asian... you should know this.

[comefightme]

Yuo bring shame to famiry, gg

[Sauron]

forget ln5. you don't need it.

come on guys, the joke is fine if you help him, otherwise it's inappropriate

I am asian so it's fine

 

 

 

And I can't answer him... gg I go home no lice to eat

so would it just be ln2 + ln2 + ln3. I don't think it can be simplified any further and if I combine the 2 ln2's then it's ln4.

yeah, pretty much. maybe there's a way with subtractions / multiplications to get the ln5 in there, but it seems completely unnecessary to me. Just add +ln5-ln5 if you're required to use it.

Thanks. I guess I'll just do ln2 + ln2 +ln3 because squeezing ln5 into there would just be adding 0.

Have you thought of negatives?  NVM i'm stupid

well it wants it in terms of ln2, ln3, and ln5. And you can't have negative logarithms with a positive base. And subtracting them would just cancel them out lol.

That's why I said i was stupid.

[rafazafar]

ln12 = 2ln 2 + ln3 . unless u need to use the ln5. which makes it more interesting.

That's what I put. Thanks

[rafazafar]

That's what I put. Thanks

another way to put it..seems stupid tho

ln12= (ln5+2ln3)-2ln2

[afyeung]

ln12= (ln5+2ln3)-2ln2

 

Lol. That wouldn't work because (ln5+2ln3) = ln5+ln9 = ln45 and ln45 - 2ln2 = ln45-ln4 != ln12

opps sorry. derped haha. oh well forget that. ill post if i remember something good.

1. ln12 = ln5²-ln3²-ln2²

2. ln12 = ln5²+(ln3²-ln2)

3. ln12 = (ln5-ln3+ln2)⁹

4. ln12 = (ln5+ln3-ln2)⁴

[afyeung]

 

 

 

1. ln12 = ln5²-ln3²-ln2²

2. ln12 = ln5²+(ln3²-ln2)

3. ln12 = (ln5-ln3+ln2)⁹

4. ln12 = (ln5+ln3-ln2)⁴

 

That's completely wrong lol. ln5^2 = ln25- ln3^2 = ln25/9 which is already less than ln12 not including the ln2^2

I left a square on the second equation's ln5 and 3 and 4 were supposed to be root of 9 and 4 but I forgot you can't mix different variables so just go with either the first or second equation.
