Hello everyone, this is my first post, so please have mercy

I've been trying to figure out how to transpose the following equations so that the value in square brackets, [ ] , is the subject. *sorry about not knowing how to insert a square root*

Eqn 2: A = 1 / sqr root(w^2 . R^2 . C^2 + 1) ............ [R . C]

I hope that was clear enough. This is needed for an assignment I have to email before 5pm (current time: 2pm!!) so any assistance in showing me the steps as to how to transpose these would be greatly appreciated!!

Thank you
