\(\sqrt{x-1}-3=0\)
\(\Leftrightarrow\sqrt{x-1}=3\)
\(\Leftrightarrow\sqrt{x-1}=\sqrt{9}\)
\(\Leftrightarrow x-1=9\Leftrightarrow x=10\)
ý mình là biểu thức x nhan voi căn bậc hai
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
Giai he phuong trinh
x(x+y)+can (x+y)=can (2y) [can(2y^3)+1]
8x^2-8y+2(x^3-y^3)+3=8y can(2x^3-3x+1)
tat ca deu la can bac hai
Giai cac phuong trinh sau
a)x^2- 10=0
b)2x^2- 6=0
c)x^2- can bac 5=0
Giai phuong trinh:
3+√(2x-3) =x
giup em em dang can gap a
Cho phuong trinh bac hai 4x^2-2(√10)+1=0 co hai nghiem x1,x2.Khong giai phuong trinh, hay tinh gia tri bieu thuc(√x14+8x22)+(√x24+8x12).
giai phuong trinh va he phuong trinh sau:
x2 + 5x -6=0
b{4x+5y=3
{x-3y=5
giai mau giup toi nhe cac ban
giai cac phuong trinh sau
a) x + 5 can x - 6 =0
b) x - can x + 1/4 = 0
giai cac phuong trinh sau
a) x + 5 can x - 6 =0
b) x - can x + 1/4 = 0
giai cac phuong trinh sau
a) x + 5 can x - 6 =0
b) x - can x + 1/4 = 0
