I assume we want the positive square root...so we can  write

 

√ 121y2           √ 121        √ y2                         11 y 

 _____  =      _____    *   ____       =            ______

√ 64x6              √ 64          √ x6                        8 x3

 

 

The only thing that might give you trouble is this :

 

  √ x6    =   ( x6 )1/2    =  x3

 

 

 

Did you understand, Manuel   ????

 

cool cool cool
