This is really driving me nuts, I've spent about 2 hours on and off trying to get to the given answer...With no close results.
Apologies for lack of formatted maths symbols.
The answer is given as (16/243)√6
I follow the normal process, as in: = √(8/27)^3
then go down the ((√2.√4)/(√3.√9))^3
This takes me nowhere near to (16/243)√6
If somone has the time, could you please show me how I can get to the (16/243)√6 and maybe explain the error of my process too.
It would be much appreciated
