I have this expression: $\displaystyle g = \sqrt {2\ln {{{\sigma ^2}} \over {{{2r} \over {\sqrt a }}x\log x{e^{  a{{(r + (1/2){\sigma ^2})}^2}\tau /(2{\sigma ^2})}}}}} $ I want to put this expression equal to zero so it would be something like $\displaystyle 0 = {e^{{{{g^2}} \over 2}}}  { \ldots \over \ldots }$ $\displaystyle {e^{{{{g^2}} \over 2}}}$ i put just to remove squared and 2ln from the right side How should i express this correctly?

$g = \sqrt{2\ln\left(\dfrac{\sigma^2}{\text{big mess}}\right)}$ $g = 0 \implies \dfrac{\sigma^2}{\text{big mess}} = 1$

Hmmm...your problem statement is: "Help to put Expression equal to zero" Sooo.... g = sqrt(bigmess) g^2 = bigmess g^2  bigmess = 0 There..."equal to zero" What's a big mess Skeeter? The Folies Bergeres' dressing room?
