I have an issue trying to rearrange this formula.
X = ( Z / (1 + 81 ^ ( ( A + B/2 - Y ) / B ) ) )
I am trying to rearrange this formula to make A the subject i.e. A = ......
I can rearrange this formula to start with to get:
Z / X - 1 = 81 ^ ((A + (B/2) - Y) / B)
I also know that X = Y ^Z and that Y = X (1/Z). But i believe in this case you need to you LOG but i would struggle with this next step.
Your help here would be appreciated.
