Question

( rightarrow(sin x) )
( x^{1}+4 y^{3}+9 z^{3}=10 x y z quad(4) )
To find ( frac{(x+2 y)^{2}}{x y}+frac{(2 y+3 z)^{2}+(3 z+x)^{2}}{y z} )
( therefore fleft(frac{-32}{x y}right)^{2}+frac{(-x)^{2}}{y^{2}}+frac{(-2 y)^{2}}{2 x} )
( frac{9 z^{2}}{x y}+frac{x^{2}}{y^{2}}+frac{4 y^{2}}{2 x} Rightarrow frac{92^{3}+x^{3}+4 y^{3}}{x y z} )
5
( frac{18 times 42}{frac{x y}{2}} )
( frac{918}{2} )
