Sorry for the horrible appearence of this question but here it goes..
17(1-(1/17^2))^0.5 = n(sqrt(2))
Where n is an integer, whose value is to be found
the closest ive gotten so far is
... but I'm not sure where to start since 17 is prime and I don't think the brackets can be expanded because the sqrt() surrounding the right-most part of the expression doesn't allow this as far as I'm aware
I'd prefer to have the steps to complete the problem since the value for n is given at the back of the textbook (n=12).
Thanks in advance,
