$$z = \operatorname{asin}^{3}{\left(\frac{x y}{2} \right)}$$
Detail solution
Given the equation:
$$z = \operatorname{asin}^{3}{\left(\frac{x y}{2} \right)}$$
transform:
$$z = \operatorname{asin}^{3}{\left(\frac{x y}{2} \right)}$$
Expand brackets in the right part
We get the answer: z = asin(x*y/2)^3
$$z = \operatorname{asin}^{3}{\left(\frac{x y}{2} \right)}$$
transform:
$$z = \operatorname{asin}^{3}{\left(\frac{x y}{2} \right)}$$
Expand brackets in the right part
z = asinx*y/2^3
We get the answer: z = asin(x*y/2)^3
