8. Lot of people find his behavious confusing.

a, Có \(\left(x^2-9\right)^2\)≥0   ∀ x ∈ Z

           |y-2| ≥0   ∀ y ∈ Z

⇒ Gía trị nhỏ nhất A=-1. Dấu ''='' xảy ra khi:\(\left(x^2-9\right)^2\)+|y-2|=0

                                                                 ⇒   \(x=3\) ;  \(y=2\)

Vậy.....

b, Có \(x^4\) ≥ 0 ∀ x ∈ Z

         3\(x^2\) ≥ 0 ∀ x ∈ Z

 ⇒ Giá trị nhỏ nhất của B=2. Dấu ''='' xảy ra khi: \(x^4\)+3\(x^2\)=0

                                                                         ⇒  \(x^2\left(x^2+3\right)\)=0

                                                                         ⇒  \(x^2\)             =0

                                                                         ⇒   \(x=0\)

Gọi độ dài ba cạnh của tam giác đó lần lượt là a,b,c và các đường cao tương ứng là x,y,z.

⇒ ax=by=cz(=2S△)

x:y:z=3:6:4 ⇒ \(\dfrac{x}{3}\)=\(\dfrac{y}{6}\)=\(\dfrac{z}{4}\)⇒ \(\dfrac{ax}{3a}=\dfrac{by}{6b}=\dfrac{cz}{4c}\)

Mà ax=by=cz

⇒ 3a=6b=4c ⇒ \(\dfrac{3a}{24}=\dfrac{6b}{24}=\dfrac{4c}{24}\) ⇒ \(\dfrac{a}{8}=\dfrac{b}{4}=\dfrac{c}{6}\)

Có: Chu vi tam giác là 36cm ⇒ a+b+c=36

Áp dụng tính chất dãy tỉ số bằng nhau ta có:

           \(\dfrac{a}{8}=\dfrac{b}{4}=\dfrac{c}{6}\)=\(\dfrac{a+b+c}{8+6+4}=\dfrac{36}{18}=2\)

     \(\dfrac{a}{8}=2\)              a=2.8            a=16

➩  \(\dfrac{b}{4}=2\)      ➩    b=2.4    ➩    b=8

      \(\dfrac{c}{6}=2\)             c=2.6            c=12

Vậy độ dài 3 cạnh của tam giác lần lượt là 16cm;8cm;12cm.
