Sorry for the confusion.

2.*sq.rt (2/3) = sq.rt. [2*(2/3)] ? Yes or No ?

means 2 multiplied by the square root of 2/3 = square root of 2 multiplied by 2/3. So in one side the 2 is outside the square root on the other 2 is inside the square root.

* is multiplication, []are brackets, Its not the Gaussklammer.
'.' is full stop.
It is not a riddle! Its just a maths curiosity which looks odd and that it is wrong but it is right.
