Question 19
$x \alpha z^{2}$
$y \alpha \frac{1}{z^{3}}$
$\sqrt{x} \alpha z$
$\frac{1}{^{3}\sqrt{y}} \alpha z$
$\sqrt{x} \alpha \frac{1}{^{3}\sqrt{y}}$
Raise both sides to the power of 6
$x^3 \alpha \frac{1}{y^{2}}$
$x \alpha z^{2}$
$y \alpha \frac{1}{z^{3}}$
$\sqrt{x} \alpha z$
$\frac{1}{^{3}\sqrt{y}} \alpha z$
$\sqrt{x} \alpha \frac{1}{^{3}\sqrt{y}}$
Raise both sides to the power of 6
$x^3 \alpha \frac{1}{y^{2}}$
