the question is asking what is;

'root 6' x 'root 6' x 'root 6'.

'root 6' x 'root 6' = 6      as if you square a square root you are just left with the number.                                            (this is probably the maths you have not understood).

this 6 is then multiplied by the final 'root 6', which = 6 'root 6'
