Giải câu g,h,i,k,l,m thôi ạ

Answer 1

Câu g,h,i,k,l,m của bài 1 hay bài 2 ấy bạn?

Answer 2

g) \(\sqrt{7-4\sqrt{3}}+\sqrt{4-2\sqrt{3}}=\sqrt{\left(2-\sqrt{3}\right)^2}+\sqrt{\left(\sqrt{3}-1\right)^2}=\left|2-\sqrt{3}\right|+\left|\sqrt{3}-1\right|=2-\sqrt{3}+\sqrt{3}-1=1\)

h) \(\sqrt{11+6\sqrt{2}}-\sqrt{3-2\sqrt{2}}=\sqrt{\left(3-\sqrt{2}\right)^2}-\sqrt{\left(\sqrt{2}-1\right)^2}=3-\sqrt{2}-\sqrt{2}+1=4\)

i) \(\sqrt{15+6\sqrt{6}}+\sqrt{15-6\sqrt{6}}=\sqrt{\left(3+\sqrt{6}\right)^2}+\sqrt{\left(3-\sqrt{6}\right)^2}=3+\sqrt{6}+3-\sqrt{6}=6\)

k) \(\sqrt{33+8\sqrt{2}}-\sqrt{33-8\sqrt{2}}=\sqrt{\left(4\sqrt{2}+1\right)^2}-\sqrt{\left(4\sqrt{2}-1\right)^2}=4\sqrt{2}+1-4\sqrt{2}+1=2\)
