Find the direction cosines of the normal to the plane 4x-3y+5z=25 and the length of the perpendicular from the origin on this plane

Find the constant of variation and write the equation of variation for each of the examples given below : zα 1/w . When z = 2.5, then w = 24

Solve the following system of linear equaltions, by Gaussian elimination method: 4x+3y+6z=25,x+5y+7z=13,2x+9y+z=1 .

Co-ordiantes of the point of intersection of the line (x+1)/1 = (y+3)/3 = (z-2)/-2 with the plane 3x+4y +5z=25 are

If, 2^(x+y-2z)=8^(8z-5-y), 5^(4y-6z)= 25^(y+z), 3^(4x-3z)=9^(x+z) then the value of 2x+3y+5z is: यदि 2^(x+y-2z)=8^(8z-5-y), 5^(4y-6z)= 25^(y+z), 3^(4x-3z)=9^(x+z) है, तो 2x+3y+5z का मान क्या होगा ?
