Question

Answer 1

\(A=6\sqrt{2}+15\sqrt{2}-35\sqrt{2}+30\sqrt{2}=16\sqrt{2}\)

\(B=21\sqrt{3}-10\sqrt{3}+32\sqrt{3}+33\sqrt{3}=76\sqrt{3}\)

Answer 2

\(A=2\sqrt{18}+3\sqrt{50}-5\sqrt{98}+6\sqrt{50}\)

\(=6\sqrt{2}+15\sqrt{2}-35\sqrt{2}+30\sqrt{2}\)

\(=16\sqrt{2}\)

\(B=7\sqrt{27}-2\sqrt{75}+8\sqrt{48}+3\sqrt{363}\)

\(=21\sqrt{3}-10\sqrt{3}+32\sqrt{3}+33\sqrt{3}\)

\(=76\sqrt{3}\)
