try to let u=x^1/4
so you have
solve for u
and then solve for x
This will require logarithms. If you rewrite this as 1/2 log 2x - 1/4 log x = 3, this will help. The final answer for x is x=81/16

we check these because we raised both sides to an even power
we don't need logarithms
so if we have x=1, does the equation hold?
2(1)-1=3 so 1 is not a solution
so if we have x=81/16, does the equation hold?
2(81/16)^(1/2)-(81/16)^(1/4)=2(9/4)-(3/2)=9/2-3/2=6/2=3 so x=81/16 is our only solution
Sorry. I am taking Linear Algebra right now and it has been about 15 years since I took algebra, so I think in terms of logs when I see that. Glad you were able to figure it out. :)
