cac bạn nhớ làm giup minh voi mai minh kiem tra mon toan roi
tim cac so x,y,z thoa man dang thuc :
\(\sqrt{\left(x-\sqrt{2}\right)^2}+\sqrt{\left(y+\sqrt{2}\right)^2}+Ix+y+zI=0\)
Tim x biết:
a) \(8\sqrt{x}-3\sqrt{\frac{4}{81}}=5,2\)
b)\(12-3x^2=10+\sqrt{\frac{25}{16}}\)
Rút gọn : A=\(\left(1-\frac{\sqrt{x}}{\sqrt{x}+1}\right):\left(\frac{2+\sqrt{x}}{x-5\sqrt{x}+6}+\frac{3+\sqrt{x}}{\sqrt{x}-2}-\frac{2+\sqrt{x}}{\sqrt{x}-3}\right)\)
1. Tìm x:
a/\(\sqrt{\dfrac{x-1}{x-3}=2}\)
b/\(\sqrt{\left(x-2\right)^2=7}\)
2. Tính:
\(\dfrac{\sqrt{6}+\sqrt{10}}{3+\sqrt{15}}\)
Tim x ,y biet
a) x+\(\frac{1}{x}=1\)
b)x+\(\frac{2}{x}=5\)
c)x\(\sqrt{3}+3=x\sqrt{3}-x\)
d)\(\left(x-2\right)\sqrt{25n^2+5}+y-2=0\)
