z = k x 3 y 2
If so, we plug in the original data to find k, then so from there thus we have
172 = k ( 6 2 ) ( 6 3 )
which given us
k=0.02212
Now we plug this in to the top equation and plug in the new x and y.
z = ( 0.02212 ) ( 4 3 ) ( 3 2 ) = 12.74

Solve 2 x = x 2
I've been asked to solve this and I've tried a few things but I have trouble eliminating x. I first tried taking the natural log:
x ln ( 2 ) = 2 ln ( x )
ln ( 2 ) 2 = ln ( x ) x
I don't know what to do from here so I decided to try another method:
2 x = 2 log 2 ( x 2 )
x = log 2 ( x 2 )
And then I get stuck here, I'm all out of ideas. My guess is I've overlooked something simple…
