Hello,

I have two equations that I want to reaarange, one a power, the other a log. I can solve the orignal equations but am getting stuck trying to make x the subject. Any help would be appreciated.

eq. 1: y= 4.3316x0.4671

To solve this (for x=8) I did the following: 4.3316 * 80.4671

= 8^(1/10 000) PWR 4671

= 4.3316 *2.64

= 11.44

I think this is right but don't know how to rearrange to get x= ?

Eq 2. y=9.5818ln(x) - 9.5878

Can solve this ok but stuck on same point - getting x=

Thanks
