1. [/latex]

guys to get y on its own, its obvious that you divide z by the whole part in the bracket. But what happens to the power of (x/z), and if it changes could you tell me why please

thanks

Nothing happens to it, the whole expression in the outer brackets is moved en masse to the denominator.

If you wish to change the power to that you need to invert the fraction within the power, so to speak.

Ok ignore the above equations

the question asks me to simplify by setting to "A"
But my dilemma is i have not

So how does relate to ?

And when you know that you can use

Im not sure but would you swap the x and z and then the power turns to its minus. I cant realy see how this has been simplified though
