Bài 1 : Tìm GTNN của : \(A=\left|x+8\right|+\left|2x+7\right|+\left|3x+6\right|+\left|4x-7\right|+\left|3x-6\right|+\left|2x-7\right|+\left|x-8\right|-100\)
Tìm x \(\left(2x-1\right)^6=\left(2x-1\right)^8\)
Tìm x biết:
a) \(\left|x+2\dfrac{1}{2}\right|=\left|3x+1\right|\)
b) \(\left|2x-6\right|+\left|x+3\right|=8\)
c) \(2.\left|x+2\right|+\left|4-x\right|=11\)
Tìm x biết
\(\left(2x-1\right)^6=\left(2x-1\right)^8\)
Tìm x
\(\left(2x-1\right)^6=\left(2x-1\right)^8\)
Tìm x và y biết:
d)\(-1\frac{2}{3}-\left(\left|2x\right|+\frac{5}{6}\right)=\)\(-2\)e)\(\left(-\frac{1}{2}+\frac{1}{3}\right):\left|1-2x\right|-1\frac{1}{4}:\left(-\frac{5}{8}\right).\left(-\frac{1}{2}\right)^2=\frac{1}{3}\)
c)\(\left|2x-1\right|+\left|2y+1\right|+\left|2x-y\right|=0\)b)\(\left|2x-1\right|=2x-1\)
a)\(\left|x-3\right|=x+4\)
\(\left(x-1\right)^6=\left(x-1\right)^8\)
b) \(\left(2x+1\right)^4=\left(2x+1\right)^8\)
Tìm số hữu tỉ x biết
\(\left(2x-1\right)^6=\left(2x-1\right)^8\)
