`(4x-2y+z)(5x-5y+z)`

Simplify : (Use formulae) (4x-5y+6z)^2+(4x+5y-6z)^2

The system of equations 4x+y+2z=5, x-5y+3z=10, 9x-3y+7z=20 has

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 ?

x+y+z=1 x-2y+3z=2 5x-3y+z=3
