If the problem is ³ = 4 or the cube root of x^2 = 4



        

                  ³³ = 4³    let us undo cube root 

                                x^2 = 64    extract the sqrt

                           sqrt x^2 = sqrt 64

                                  x = 8

 



Checking : x = 8



      ³ = 4  

       ³ = 4

    ³ = 4

                     4 = 4 ----------->>True 





Therefore x = 4
