The correct answer is: 51.
\(\frac{x-\frac{1}{8}}{\frac{1}{8}}=\frac{y}{-\frac{1}{4\sqrt2}}=\frac{z}{0}....L_1\)
or
\(\frac{x-\frac{1}{8}}{1}=\frac{y}{-\sqrt2}=\frac{z}{0}....(i)\)
\(=\frac{\sqrt2}{\sqrt{32+16+54}}=\frac{!}{\sqrt51}\)
d–2 = 51
Method used for separation of mixture of products (B and C) obtained in the following reaction is: 
The shortest perpendicular distance from the point to the given plane is the distance between point and plane. In simple terms, the shortest distance from a point to a plane is the length of the perpendicular parallel to the normal vector dropped from the particular point to the particular plane. Let's see the formula for the distance between point and plane.
