Hi i having some difficulty in transpoing the below formula
the question asks me to Change the subject of the formula to E
..........Pie E
P = e √1- EČ
Many Thanks
Richard

I will guess that you mean the following:
. . . . .$\displaystyle P\, =\, \frac{\pi e E}{e\sqrt{1\, -\, E^2}}$
If so, then a good first step would be to cancel off the common factor of "e" (from the "pi times e times E" in the numerator and the "e" in front of the radical in the denominator). Then multiply through by the denominator, and square both sides to get rid of the radical. Multiply things out to get:
. . . . .$\displaystyle P^2\, -\, P^2 E^2\, =\, {\pi}^2 E^2$
Add the P^2 E^2 to the right-hand side, factor out the E^2, and divide through by $\displaystyle P^2\, +\, {\pi}^2$. Then take the square root of each side, remembering the "plus, minus" on the left-hand side.
