Marks: +1, -0

Which of the following is the correct expression for maximum possible speed of a car on a banked road?

$v_{\max } = (Rg\;{µ _{s} + \tan ⁡θ }/{1−µ _{S}\tan ⁡θ }) ^{1\/ 2}$
$v_{\max } = (Rg\;{√{µ _{S} + \tan ⁡θ }}/{√{1−µ _{S}\tan ⁡θ }})$
$v_{\max } = (Rg\;{µ _{S} + \tan ⁡θ }/{1−µ _{S}\tan ⁡θ })$
$v_{\max } = √{µ _{s}Rg}$
