Answer 1

Answer:

Cannot sorry

Step-by-step explanation:

Answer 2

By the given question   $Sin^-1(x)+Sin^-1(y)+Sin^-1(z)=\frac{3\pi }{2}$

we know that  $Sin^-1$  functions range lies from  $[\frac{-\pi }{2} ,\frac{\pi }{2} ]$

Therefore the Maximum value of each $Sin^-1$ function is  $\frac{\pi }{2}$

then to satisfy the given question;      $Sin^-1(x)=Sin^-1(y)=Sin^-1(z)=\frac{\pi }{2}$

If the value of   $Sin^-1(x)=\frac{\pi }{2}$ then the value of $x=1$

therefore  $x=y=z=1$

this implies $(x+y+z)^2=(1+1+1)^2=3^2=9$

Therefore our final answer is 9
