Respuesta :
h(10) = 2(10) - 8
h(10) = 12
g(12) = root 12 - 4
g(12) = root 8
g(h(10)) = 2 root 2
h(10) = 12
g(12) = root 12 - 4
g(12) = root 8
g(h(10)) = 2 root 2
[tex]\bf \begin{cases}
g(x)=\sqrt{x-4}\\
h(x)=2x-8\\
---------\\
h(10)=2(10)-8\\
\qquad \qquad 12
\end{cases}
\\\\\\
g(~~h(10)~~)\implies g(12)=\sqrt{(12)-4}
\\\\\\
g(12)=\sqrt{8}\implies g(12)=\sqrt{2^2\cdot 2}\implies g(12)=2\sqrt{2}[/tex]
