Maths Formula Help 1

[osx99]

I'm unsure which is the most appropriate forum for this question so thave opted for the here

I have a formula...

S * [a ^n(1-X)] * [b ^nX] = S

Can someone help me with the steps to get X = ?

I have given this a few tries and can get to
a^n = b^(-nX) - a^(-nX) but am struggling to get any further

Many thanks
Os

Sorry, that link didn't work quite as it should have. Copy and paste the whole line into your browser address bar.

Hi,

Is this Excel or what application?"

Are you doing this on the sheet in a cell formula or is this VBA in a macro?
