I hope I didn't make any mistakes...
Because log(a) + log(b) = log(ab)
Because 10^log(a) = a
So the positive value is x = 1.

Ok, I know there's gotta be an easier way to do this...
so:
Moving on...
And now the finale:
Possibly one of the most round-about ways of getting the answer...

The last one's a bit easier.
2log12 + 3 log5 - log15 - log150
log(12²) + log(5³) - log15 - log150
log[(2x2x3x2x2x3 x 5x5x5)/(3x5 x 2x5x3x5)]
log[2x2x2]

Why did the vector cross the road?
It wanted to be normal.

I'm sure there's an easier way to do it, I just always take the long way around.
