Coefficient of` x^3y^5z^1` in `(2x-3y+4z)^9` is

The coefficient of x^(2)y^(5)z^(3) in the expansion of (2x+y+3z)^(10) is

The coefficient of x^(2)y^(4)z^(2) in the expansion of (2x-3y+4z)^(9) is

If 2x = 3y = 4z, find x:y: z.

Find the equation of the plane through the line of intersection of the planes x+y+z=1 and 2x+3y+4z=5 which is perpendicular to the plane x-y+z=0

Solve the following set of equations 2x+3y -z = 9; x +y +z = 9; 3x - y - z = -1 .

The angle between two planes x+2y+2z=3 and -5x+3y+4z=9 is

(3x+4y+5z)(4x+3y+4z)

2x = 3y = 4z, x: y: z

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 ?
