Exercice 5
Simpllifier les expressions suivantes:
\[
I=2\sqrt{18}-3\sqrt{50}+5\sqrt{8}\ ;\ J=(\sqrt{5}+\sqrt{2})^2+(\sqrt{5}-\sqrt{2})^2
\]
\[
K=\sqrt{\sqrt{9}+2\sqrt{2}}\times\sqrt{3-\sqrt{8}}\times\sqrt{(2022)^2}\ ;\ L=(\sqrt{3}+2)^2\times(7-4\sqrt{3})\times 2023
\]
\[ M=\frac{\sqrt{15}\times\sqrt{42}\times\sqrt{44}}{\sqrt{77}\times\sqrt{18}\times\sqrt{5}}
\]
