x = (16/3)^(6/5) = 7.454155933.....

Why? Re-writing what I think you meant :

(3/4) x^(1/2) = 4/x^(1/3). Therefore x^(5/6) = 16/3. Thus:

x = (16/3)^(6/5) = 7.454155933..... QED.

Live long and prosper.

3/4x^(1/2)=4x^(-1/3)
3/4/4=x^(-1/3)/x^(1/2)
3/16=1/x^(1/2)
16/3=x^(1/2)
(16/3)^2=x
x=28.44
hope u understand
