You want to say 


Solve this equation, &nbsp;<U>please</U>!". &nbsp;Isn't ??


(x-3)^3/2 = 8.
------------------------------------------------------------


{{{(x-3)^(3/2)}}} = {{{8}}}.


Square both sides. &nbsp;You will get


{{{(x-3)^3}}} = {{{64}}}.


Now take the cubic root from both sides. &nbsp;You will get


x - 3 = {{{root(3, 64)}}} = 4.


The solution is &nbsp;x = 7.


Check it yourself, &nbsp;please.
