    i mean \[n=\frac{ IR }{ e-Ir }\]

    \[n= \frac{ -IR }{ Ir - E }\]

    because the only option there are this. n= IR( Ir - E ) n= \[\frac{ -R }{ Ir - E }\] n=\[\frac{ IR }{ Ir + E }\]

    \[1st: I(nr+R)=n e\] \[2nd: Inr+IR=n e\] \[3rd:IR=n e-Inr\] \[4th: IR=n(e-Ir)\] \[5th: n=\frac{ IR }{ e-Ir }\]
