Solution

The correct option is A $- 345 x^{5} y^{3} z^{3}$
$(23 x^{2} y^{2} z) \times (- 15 x^{3} y z^{2})$
$= - 345 ‬ x^{2 + 3} y^{2 + 1} z^{1 + 2}$
$= - 345 x^{5} y^{3} z^{3}$

Simplify the expression: \frac{52 w x y z (x y + y z + x z + y^{2}) (z + x)}{104 x y (x y z + x z^{2} + y z^{2} + y^{2} z)}

(x^{2} y + y^{2} z + z^{2} x) (x y^{2} + y z^{2} + z x^{2}) > 9 x^{2} y^{2} z^{2}

(x^{2} y + y^{2} z + z^{2} x) (x y^{2} + y z^{2} + z x^{2})

Let x, y, z be positive reals. Which of the following implies x = y = z?

(I) x $^{3}$ + y $^{3}$ + z $^{3}$ = 3xyz

(II) x $^{3}$ + y $^{2}$ z + yz $^{2}$ = 3xyz

(III) x $^{3}$ + y $^{2}$ z + z $^{2}$ x = 3xyz

(IV) (x + y + z) $^{3}$ = 27xyz

x, y, z

x = y = z ?

x^{3} + y^{3} + z^{3} = 3 x y z

x^{3} + y^{2} z + y z^{2} = 3 x y z

x^{3} + y^{2} z + z^{2} x = 3 x y z

(x + y + z)^{3} = 27 x y z
