giai phuong trinh (x-1)^2016+(x-2)^2016=1
cac ban lam giup bai nay cho minh vs. minh dang can gap. thank you nhiu
so gia tri cua x thoa man x^2+\(\frac{1}{x^2}\) =2
giup minh vs minh se tik cho cac ban nha
(\(\frac{x-2\sqrt{x}-1}{x-4}\) - 1 ) / (\(\frac{4-x}{x-\sqrt{x}-6}\) - \(\frac{\sqrt{x}-2}{3-\sqrt{x}}\)- \(\frac{\sqrt{x}-3}{\sqrt{x}+2}\) )
Cac ban oi giup mk nha
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 mik 1/0*9/0*9%
voi a,b,c,d, la cac so duong thoa man a*b = c*d =1 chung minh bat dang thuc : ( a+b )*( c+d ) +4 >= 2*( a+b+c+d ) cac ban oi giup minh voi OK
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 >>>
Tim nghiem tu nien cua pt :2y=1+x+x2+x3
