Lời giải:
\(\sqrt{x+3+2\sqrt{x+2}}+\sqrt{2-x^2+2\sqrt{1-x^2}}=\sqrt{(\sqrt{x+2}+1)^2}+\sqrt{(\sqrt{1-x^2}+1)^2}\)
\(=|\sqrt{x+2}+1|+|\sqrt{1-x^2}+1|=\sqrt{x+2}+\sqrt{1-x^2}+2\)
ĐKXĐ: \(\left\{\begin{matrix} x+2\geq 0\\ 1-x^2\geq 0\end{matrix}\right.\Leftrightarrow \left\{\begin{matrix} x\geq -2\\ -1\leq x\leq 1\end{matrix}\right.\Leftrightarrow -1\leq x\leq 1\)
