hi
i have a equation which i dont know how to solve it, as i have never seen this equation before !!
question
given : V=B-q/k In(r-1)
make r subject of the formula ?
could you please explain what they want exactly
thanks

They want you to solve for r in terms of the other pronumerals. I suggest that you first attempt to make ln(r-1) the subject.
By the way, your expression is ambiguous. Is it meant to be V=B-q/[k In(r-1)] or V=[B-q/k] In(r-1) ....?? Or V=(B-q)/[k In(r-1)] or V=B-(q/[k In(r-1)]) etc. etc. Please use bracketes, or take the couple of minutes to learn how to use latex (click on the appropriate link in my signature).
$\displaystyle \displaystyle V=\left(B - \frac{q}{k}\right) \cdot \ln(r-1)$
$\displaystyle \displaystyle \frac{V}{B - \frac{q}{k}} = \ln(r-1)$
$\displaystyle \displaystyle e^{\frac{V}{B - \frac{q}{k}}} = r - 1
$
$\displaystyle \displaystyle 1 + e^{\frac{V}{B - \frac{q}{k}}} = r$
I hope you do NOT mean that the only equations you can solve are those that you have seen before!
By the way, it is "ln" (small L) NOT "In", for natural logarithm.question
