Solving a log equation for two variables
Goal is to find both β and ω. I already have the answer here, but I'm confused as to how to get it.
log 6 250 log β 2 = 3 log β ω
This is what I did:
log 6 250 = log β ω 3 + log β 2
log 6 250 = log β 2 ω 3
log 250 log 6 = log 2 ω 3 log β
And I am stuck here. The answer states that ω = 5 and β = 6, which after entering it, is correct, but I don't know how it got to that point.
Looking directly at the last part I ended up with, it seems like you're supposed to equate the tops to one another and bottoms to one another, which would get you the answer, but with another example, that clearly does not work:
log 64 log 4 = log 27 log 3
64 27 , 4 3
How would one solve this problem, and is the path I went correct?

From:
log β ( 2 w 3 ) = log 6 ( 250 ), we can set β = 6 since we simply want to find a solution and not all solutions.
Equating 2 w 3 = 250 lets us solve for a unique w.
