Sửa đề:

a) \(A=5-\left(2x-1\right)^2\le5\left(\forall x\right)\)

Dấu "=" xảy ra khi: \(\left(2x-1\right)^2=0\Leftrightarrow x=\frac{1}{2}\)

Vậy \(Max_A=5\Leftrightarrow x=\frac{1}{2}\)

b) \(B=\frac{1}{\left(x-1\right)^2+3}\le\frac{1}{3}\left(\forall x\right)\)

Dấu "=" xảy ra khi: \(\left(x-1\right)^2=0\Rightarrow x=1\)

Vậy \(Max_B=\frac{1}{3}\Leftrightarrow x=1\)

(-5) mu 222 < 3 mu 333 

chúc bạn học giỏi

\(\Rightarrow\)

\(\text{Ta có : }\)

\(\left(-5\right)^{222}< 3^{333}\)

\(\text{Chúc bạn học tốt ! }\)

\(B=2-\left|x+\frac{5}{6}\right|\)

\(\Leftrightarrow\left|x+\frac{5}{6}\right|=0\)

\(\Leftrightarrow x+\frac{5}{6}=0\)

\("="\Leftrightarrow x=-\frac{5}{6}\Rightarrow x=2\)
