\(\sqrt{150}\) +\(\sqrt{1,6}\cdot\sqrt{60}+4,5\sqrt{2\dfrac{2}{3}}-\sqrt{6}\)
=5\(\sqrt{6}\)+4\(\sqrt{6}\)+3\(\sqrt{6}\)-\(\sqrt{6}\)=(5+4+3-1).\(\sqrt{6}\)=11\(\sqrt{6}\)
\(\sqrt{150}\) +\(\sqrt{1,6}\cdot\sqrt{60}+4,5\sqrt{2\dfrac{2}{3}}-\sqrt{6}\)
=5\(\sqrt{6}\)+4\(\sqrt{6}\)+3\(\sqrt{6}\)-\(\sqrt{6}\)=(5+4+3-1).\(\sqrt{6}\)=11\(\sqrt{6}\)
Tính :
\(\sqrt{150}+\sqrt{1,6}.\sqrt{60}+4,5\sqrt{2\frac{2}{3}}-\sqrt{6}\)
\(\frac{1}{2}\sqrt{48}-2\sqrt{75}-\frac{\sqrt{33}}{11}+5\sqrt{1\frac{1}{3}}\)
\(\sqrt{150}+\sqrt{1,6}.\sqrt{60}+4,5\sqrt{2\frac{2}{3}}-\sqrt{6}\)
rút gọn
giúp mình rút gọn bài này với
\(\sqrt{150}+\sqrt{1,6}.\sqrt{60}+4,5\sqrt{\frac{4}{3}}-\sqrt{6}\)
Tính giá trị biểu thức:
a) \(\left(\sqrt{8}-3\sqrt{2}+\sqrt{10}\right).\left(\sqrt{2}-3\sqrt{0,4}\right)\)
b) \(\frac{\sqrt{3+\sqrt{5}}}{\sqrt{2}}-\frac{\sqrt{5}-1}{2}\)
c)\(\sqrt{150}+\sqrt{1,6}.\sqrt{60}+4,5.\sqrt{2\frac{2}{3}}-\sqrt{6}\)
Thực hiện phép tính
1. \(\frac{1}{2}\sqrt{48}-2\sqrt{75}-\frac{\sqrt{33}}{\sqrt{11}}+\sqrt{84}\)
2. \(\sqrt{150}+\sqrt{1,6}\sqrt{60}+4,5\sqrt{2\frac{2}{3}}-\sqrt{6}\)
Mấy bạn biết làm thì giúp An nhé! Giải từng bước nha, đừng giải tắt. An cảm ơn nhìu lắm !!! <3
b1,tính
a,\(\sqrt{\left(\sqrt{7}-4\right)^2}+\sqrt{8-2\sqrt{7}}\)
b,\(\sqrt{\left(\sqrt{5}-2\right)^2}+\sqrt{6+2\sqrt{5}}\)
b2,rút gọn các biểu thức sau
a,\(5\sqrt{\dfrac{1}{5}}+\dfrac{1}{2}\sqrt{20}+\sqrt{5}\)
b,\(\sqrt{\dfrac{1}{2}}+\sqrt{4,5}+\sqrt{12,5}\)
c,\(\sqrt{20}-\sqrt{45}+3\sqrt{18}+\sqrt{72}\)
d,\(0,1\times\sqrt{200}+2\times\sqrt{0,08}+0,4\times\sqrt{50}\)
\(\left(\dfrac{1}{2}\sqrt{\dfrac{1}{2}}-\dfrac{3}{2}\sqrt{4,5}+\dfrac{2}{5}\sqrt{50}\right):\dfrac{4}{15}\sqrt{\dfrac{1}{8}}\) tính
1) cho B= \(\dfrac{1-5\sqrt{x}}{x-1}\)
Tìm x thuộc R để B nguyên
2) Tính
+ \(\sqrt{8-2\sqrt{15}}.\left(\sqrt{60}+6\right):2\sqrt{3}\)
+ \(\sqrt{5-\sqrt{21}}-\sqrt{\dfrac{7}{2}}\)
Tính:
1) \(\dfrac{3}{1-\sqrt{2}}+\dfrac{\sqrt{2}-1}{\sqrt{2}+1}\)
2) \(\dfrac{\sqrt{5}-1}{\sqrt{5}+1}+\dfrac{6}{1-\sqrt{5}}\)
3) \(\dfrac{\sqrt{2}+\sqrt{3}}{2-\sqrt{6}}+\dfrac{\sqrt{3}-\sqrt{2}}{\sqrt{6}+2}\)
4) \(\dfrac{3+\sqrt{3}}{\sqrt{3}}+\dfrac{\sqrt{6}-\sqrt{3}}{1-\sqrt{2}}\)
5) \(\dfrac{2-\sqrt{2}}{1-\sqrt{2}}+\dfrac{\sqrt{2}-\sqrt{6}}{\sqrt{3}-1}\)
