giup dum minh voi nha cac ban :
\(\sqrt{4+\sqrt{5.\sqrt{3+5.\sqrt{48-10\sqrt{7+4\sqrt{3}}}}}}\)
Tim x trong cac ti le thuc:
a> 1,2 : 0,8 = [-3,6] : [3x]
b> 12 : 5 = x : 1,5
c> x : 2, 5 = 0,03 : 0,75
d> 3,75 : x = 4,8 : 2,5
e> 2- x/1 = 3x - 1/-3
<<<Giup mk vs cac ban >>>
cac ban giai giup mk bai nay nha
\(\sqrt{19+8\sqrt{3}}-\sqrt{19-8\sqrt{3}}=?\)
\(\sqrt{x+2\sqrt{x-1}}+\sqrt{x-2\sqrt{x-1}}=?\)
Bài 1 :Rút gọn:
H=(\(\frac{3}{\sqrt{2}+1}+\frac{14}{2\sqrt{2}-1}-\frac{4}{2-\sqrt{2}}\))(.\(\sqrt{8+2}\))
giup mk vs cac ban oi chieu nay mk phai hk ruj
cac ban oi giup minh bai toan phan tich da thuc thanh nhan tu x^7+x^5+1
x^2-2(-1 + 3)x + (-1) + 3 = 0 giup minh vs cac ban oi
so gia tri cua x thoa man x^2+\(\frac{1}{x^2}\) =2
giup minh vs minh se tik cho cac ban nha
\(\frac{x+\sqrt{xy}}{\sqrt{x}-\sqrt{y}}\)
cac ban chi cach triet tieu giup minh ik =')))
tim max cua\(\sqrt{14-x}+\sqrt{x-10}\).
cac ban giup minh giai nhe, minh can rất gấp ạ
