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.
(8/27)^3/2
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
= ((2√2)/(3√3))^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
Thank you
ok, thanks : )
I can follow your thinking mainly, but have a question.
Why is it that you would have (√6/3)^9 and not (√6/√3)^9.
Maybe I just can't see the wood for the trees now, after so long tacklilng this one... : /
Edit:
well, infact, I can't see how you get to the (√6/3)^9 step, I can't see where the √6 comes from looking at the previous step...Shouldn't (2/3)^9/2 = √(2/3)^9 ? ...My poor head
