so gia tri cua x thoa man (x^2+1)+/x-1/+/x^3+1/=0
tick nhanh cho mk vs
bai 1 so cac gia tri nguyen cua x de gia tri tuyet doi cua x + gia tri tuyet doi cua x-2 =0
bai 2 so cac gia tri nguyen cua x thoa man gia tri tuyet doi cua x-3 + gia tri tuyet doi cua 8-2x = 1 là
So gia tri cua x thoa man ( x^2+1) + | x-1 | + | x^ 3 + 1| = 0
1. so x>0 thoa man \(\frac{5}{x}=\frac{x+1}{22}\)
2. GTLN cua x thoa man \(5^{\left(x-2\right)\left(x+3\right)}\)
3. Gia tri x<0 thoa man /\(x^2+50\)/=/\(-2x^2\)-1/
4. Gia tri nguyen cua x thoa man \(\left(3x-4\right)^5\)=\(^{\left(3x-4\right)^7}\)la x=
5. So gia tri cua x thoa man /x-2014/+/x-2015/=0
6. Gia tri cua x de bieu thuc A=\(\frac{x-3+5}{3-x+2}\)dat gia tri lon nhat la x=
gia tri cua x thoa man: (2x-1)^3=-8 cac ban ui giup mk vs ai lm dug mk like cko
cho x la so nguyen thoa man : -7/25<x/30<-1/5. so gia tri cua x thoa man la
-7/25<x/30<-1/5
quy đồng mẫu
=>(-42/150)<(5x/150)<(-30/150)
vậy số giá trị là 11
gia tri cua x>1 thoa man : 1/2+1/3<x<3-1/3
giúp mik vs
x = 6 /6 ; 7/6
giúp tớ nhé
tớ bị trù 690 điểm
cảm ơn nhé
so cac gia tri cua x thoa man |x-5|/|x-3|=|x-1|/|x-3|
so gia tri cua x thoa man x^2+\(\frac{1}{x^2}\) =2
giup minh vs minh se tik cho cac ban nha
x^2 + 1/x^2 \(\ge\)2 ( AM-GM )
Mà x^2 + 1/x^2 = 2
=> x^4 = 1 => x = 1 hoặc -1
gia tri cua x>0 thoa man so doi cua x2 +1=5
x2 + 1 = 5
Ta có : x2 = 5 + 1
= x2 = 6
x = 3
