logarithm/337518: PH^t=Vk^t
I need to use logarithms to solve for t, however I am not sure what to do.
tlog(Ph)=tlog(Vk) or
log(p)*tlog(h)=log(v)*tlog(k)
I am not sure which one is right and where to go on from here. 1 solutions

If there were parentheses like this:
Then your first attempt would have been correct. As it stands though, neither is correct.
Taking the log of both sides was absolutely the correct thing to do. Personally, I would have taken the natural log rather than the base 10 log, but it makes no difference in the final analysis. You say to-may-to, I say to-mah-to.
Next use
to write:
Then use:
to write (and here is where we start to deviate -- note the plus signs in mine as compared to your multiplication signs. Of course, multiplying by adding is really the point of logarithms, now isn't it?):
Collect the terms with on the left and the other two terms on the right:
Factor out :
Next use:
to write:
Divide both sides by :
And that, as they say, is that. And just as an "oh by the way," the following identical relationship is true:

2Y =90-12
Y= 72/2
Y = 36 THEN PLUG IN EQUATION ABOVE 36+X=90 THEN X=90-36
THEN X = 54
