यदि `[{:(,x+y+z),(,x+z),(,y+z):}]=[{:(,9),(,5),(,7):}]` तो का x,y,z मान ज्ञात कीजिएः

Find x and y if :- [(x + y + z),(x+z),(y+z)]=[(9),(5),(7)]

If ({:(3x -y, x + 3y),(2x - z, 2y +z):}) = ({:(7,9),(5,5):}), then x + y + z equals

Find the values of x,y and z , if [{:(x+y,),(x+z,),(y+z,):}]=[{:(9,),(5,),(7,):}] .

If x = 255, y = 256, z = 257, then find the value of x^3+y^3+z^3-3xyz . यदि x = 255, y = 256, z = 257 है, तो x^3+y^3+z^3-3xyz का मान ज्ञात कीजिए ।

Find the values of x, y and z if {:[(x+y+z),(z+x),(y+z)]={:[(9),(5),(7)]

Find the values of x, y and z from the following equations : (i) [{:(4,3),(x,5):}]=[{:(y,z),(1,5):}] (ii) [{:(x+y,2),(5+z,xy):}]=[{:(6,2),(5,8):}] (iii) [{:(x+y+z),(x+z),(y+z):}]=[{:(9),(5),(7):}]

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 ?

If [[x+y+z],[x+z],[y+z]] = [[9],[5],[7]] ,then the value of x-y+z is
