Question

\(\sqrt{3\sqrt{2}-2\sqrt{3}}\)  . \(\sqrt{3\sqrt{2}+2\sqrt{3}}\)

tính !!!

Answer 1

\(=\sqrt{\left(3\sqrt{2}-2\sqrt{3}\right)\left(3\sqrt{2}+2\sqrt{3}\right)}\)

\(=\sqrt{\left(3\sqrt{2}\right)^2-\left(2\sqrt{3}\right)^2}\)

\(=\sqrt{18-12}\)

\(=\sqrt{6}\)

Answer 2

\(\sqrt{3\sqrt{2}-2\sqrt{3}}\cdot\sqrt{3\sqrt{2}+2\sqrt{3}}\)

\(=\sqrt{18-12}\)

\(=\sqrt{6}\)
