Statement I If tan^(-1) x + tan^(-1) y = pi/4 - tan^(-1) z " and " x + y + z = 1 , then arithmetic mean of odd powers of x, y, z is equal to 1/3 . Statement II For any x, y, z we have xyz - xy - yz - zx + x + y + z = 1 + ( x - 1) ( y - 1) ( z - 1)

Factorize 1+x+y-z+xy-yz-zx-xyz

If x:y=3:2 and y:z=8:9 , find x:y:z

if x+y+z=1 and xy+yz+zx=1/3 then find x:y:z

If 2^(x) = 4^(y) = 8^(z) and xyz = 288 , the value of 1/(2x) + 1/(4y) + 1/(8z) is

If x + y + z = 10, x^3+y^3+z^3=75 and xyz = 15, then find the value of x^2+y^2+z^2 -xy-yz-zx यदि x + y + z = 10, x^3+y^3+z^3=75 तथा xyz = 15 है, तो x^2+y^2+z^2 -xy-yz-zx का मान ज्ञात कीजिए।
