Xung quanh ô quân vua đang đứng có 8 ô, nên ở mỗi một bước, quân vua có 8 cách di chuyển

\(\Rightarrow\) Quân vua có \(8^3\) cách di chuyển 3 bước

Ở bước đầu tiên, quân vua có 3 kiểu đi: sang các ô xanh hoặc sang các ô đỏ

TH1: quân vua sang ô xanh: có 4 cách. Do vai trò các ô như nhau, giả sử quân vua sang ô số 1

Để sau 2 bước nữa quay về ô 0 ban đầu, ở bước tiếp theo nó phải đi vào 1 ô nằm kế ô 0 \(\Rightarrow\) có 4 cách (là các ô 2,3,7,8)

Vậy có 4.4=16 cách

TH2: Quân vua sang ô trắng (có 4 cách) giả sử là ô số 2, vẫn như trên, bước thứ 2 nó phải sang 1 ô nằm kế ô số 0 => có 2 cách

\(\Rightarrow\) 4.2 =8 cách

Vậy quân vua có \(16+8=24\) cách đi thỏa mãn

Xác suất: \(\dfrac{24}{8^3}=...\)

\(=3:\left[\dfrac{4}{9}+\dfrac{1}{2}-\dfrac{4}{3}\right]-\dfrac{1}{7}\)

\(=3\cdot\dfrac{-18}{7}-\dfrac{1}{7}=\dfrac{-55}{7}\)

a) \(\dfrac{1}{4}-3\left(\dfrac{1}{12}+\dfrac{3}{8}\right)=\dfrac{1}{4}-\dfrac{1}{4}-\dfrac{9}{8}=-\dfrac{9}{8}\)

b) \(\left(-\dfrac{2}{3}+\dfrac{3}{5}\right):\dfrac{1}{50}-30=\left(-\dfrac{2}{3}+\dfrac{3}{5}\right).50-30=-\dfrac{100}{3}+30-30=-\dfrac{100}{3}\)

5^2x-2 + 2².5² = 5³

5^2x-2 + 100 = 125

5^2x-2          = 125 - 100

5^2x-2          = 25

5^2x-2          =   5²

        2x- 2  = 2

            2x   = 2 + 2

             2x = 4

               x = 4:2

               x = 2

52x-2 + 22.52 = 53

52x-2 + 100 = 125

52x-2          = 125 - 100

52x-2          = 25

52x-2          =   52

        2x- 2  = 2

            2x   = 2 + 2

             2x = 4

               x = 4:2

               x = 2
