Giải hộ giúp mik trong hôm nay nha mọi người!:))Cảm ơn nhiều!:)))
2.Tính
a.\(\sqrt{20}+2\sqrt{45}-3\sqrt{80}+\sqrt{125}\)

Giải hộ mình trong hôm nay hoặc ngày mai nhé!:))Thanks you very much!:))))))))))))))))))))
Rút gọn
a) \(\sqrt{8+\sqrt{8}+\sqrt{20}+\sqrt{40}}-\sqrt{2}-\sqrt{5}\)
b)\(\sqrt{41+6\sqrt{6}-12\sqrt{10}-4\sqrt{5}}+2\sqrt{5}-\sqrt{3}\)
Các bạn giúp mik giải bài này trong hôm nay hoặc sáng mai nhé!Chiều mai mik phải nộp rùi!:))))))))))))

tìm x
2\(\sqrt{16x-16}\) +\(\sqrt{41-4y}\) -\(\sqrt{x-1}\) =46
các bạn giúp mik vs ạ
bài 5 sử dụng hằng đẳng thức bình phương một tổng ( hiệu) để khai phương
a)\(\sqrt{7+4\sqrt{3}}\)
b)\(\sqrt{8-2\sqrt{12}}\)
c)\(\sqrt{21+6\sqrt{6}}\)
d)\(\sqrt{15-6\sqrt{6}}\)
e)\(\sqrt{29-12\sqrt{5}}\)
g)\(\sqrt{41+12\sqrt{5}}\)
Các bạn giải giúp mik bài toán này trong hôm nay nhé!:)))
\(\dfrac{\sqrt{6-\sqrt{11}}}{\sqrt{22}-\sqrt{2}}-\dfrac{6}{\sqrt{2}}-\dfrac{3}{\sqrt{2}+1}\)
\(\sqrt{2-\sqrt{3}}-\sqrt{\dfrac{3}{2}}\)
Cảm ơn các bạn nhiềuuuuuuuuuu lắmmmmmmmmmmmmmm!:)))))))))))))))))))
rút gọn
a.\(\dfrac{5\sqrt{2}-2\sqrt{5}}{\sqrt{5}-\sqrt{2}}+\dfrac{6}{2-\sqrt{10}}\)

lm mhanh giúp mk nhé!mk đang cần gấp!
2. tìm x
a, \(3\sqrt{2x}\) + \(\sqrt{8x}\) - \(\sqrt{18x}\)= 16
b, \(\sqrt{4x+20}\) - \(3\sqrt{x+5}\) + \(\dfrac{4}{3}\) \(\sqrt{9x+45}\) = 6
