Solution

The correct option is A $x > y > z$
$x > y > z$
Because double bond length is always less than single bond length . So, ' $y$ ' value is small here.
Between ' $x$ ' and ' $z$ ', ' $x$ ' has more value because of more electronegtivity of ' $O$ ', it pulls electron of ' $H$ '. So its electronegativity decreases and bond length is more.

A = {x, y, z}

then the relation

R = {(x, x), (y, y), (z, z), (z, x), (z, y)}

A = {x, y, z}

, then the relation

R = {(x, x), (y, y), (z, z), (z, x), (x, z)}

x = sin 1 + cos 1, y = \sqrt{sin 1} + \sqrt{cos 1}

z = sin 1 - cos 1,

then which among the following relation between

x, y, z

If x, y and z are variables, verify the cyclic symmetry of the following expressions.

(1) x(y + z) + y(z + x) + z(x + y)

(2) xy(x − y) + yz(y − z) + zx(z − x)

(3) x²y(x + y) + y²z(y + z) + z²x(z + x)

(4) x³(x + y) + y³(y + z) + z³(z + x)

(5) xy²(x − y) + yz²(y − z) + zx²(z − x)

\frac{x (y + z - x)}{log x} = \frac{y (z + x - y)}{log y} = \frac{z (x + y - z)}{log z}

x^{y} y^{x} + z^{y} y^{z} - 2 x^{z} z^{x}
