1dude mene aise hi kia tha , lekin mera answer 6/√34 aa ra hai. lekin answer 3√34/17 dia hai

FUNDA1
first find the equation of the plane 4m the 3 points given and use the formula to get the perp dis
OR
FUNDA2
find the vector AB X AC(unit). The perpendicular distance will be the component of AP on this unit vector
111bhai maine kaha tha unit vector AB X AC did u take the unit vector???
1dude mene first method se kia ............. first waale se b to aana chaiye
11Plane is:
3x-4y+3z=19
hence, in vector form....... r.(3i - 4j + 3k) = 19
distance d= \left|\frac{18-20+27-19}{\sqrt{3^{2}+(-4)^{2}+3^{2}}} \right|
which turns out to be \frac{3\sqrt{2}}{\sqrt{17}}
Hope i am right....
1sorry friends mera answer aur book ka answer same hai.
mera dimaag khraab ho gaya tha
