Howling Wolf is right...Basic rule with equations is whatever you do...always do it to both sides

@sportscout: apparently that's what they call it now. when I was at school, it was solve for k...For some reason "they" think they have to change terminology every decade (or so).

@Bugmeiser: Close.. but you might want to rethink that procedur
Edit, since you postet again: I refer to this

multiply both sides by root b then turn the whole thing upside down

Im still lost lol, if someone could break down the steps it would be awesome. Once I have the method figured out im sure these will seem easy, its all new to me I have no idea how to do a or b.. I know about balancing the sides, 'the basics' I don't understand how in question 'a' how the Square root of b stays as the square root of b if it changes sides etc..

With an operation involving roots you always have 2 options:
Option 1 : solve the root (extremely unpracticable)
Option 2: use the whole thing as 1 expression (which means it doesn't change when its been "moved" to the other side
I hope that's a bit clearer

think of root b as an expression..

- it's a bit like the Time = Distance/Speed formula..

all you're doing is moving the expressions around to suit their use:

Distance = Speed.Time
Speed = Distance/Time

We broke down the first one now you have to do the rest...

Ok I think I got question 'a' figured out..

a= Sqr(b)/k
becomes
a x k = Sqr(b) xk
a x k = Sqr(b)
a x k/a = Sqr(b)/a
so
k = Sqr(b)/a

Question 'b' is harder how do I just get the 'b' from the sqr(b)? Hmm

I'd just leave it as root b

a-2= root of b over k
k(a-2) = root of b

Remember: sqr(b)*sqr(b) = b
