co hong phai nhu the

\(\left(x+\dfrac{2}{3}\right)+\dfrac{1}{11}=\left(\dfrac{10}{-33}.\dfrac{11}{8}\right).\dfrac{24}{-55}\)

\(\Rightarrow\left(x+\dfrac{2}{3}\right)+\dfrac{1}{11}=\dfrac{-5}{12}.\dfrac{24}{-55}\)

\(\Rightarrow\left(x+\dfrac{2}{3}\right)+\dfrac{1}{11}=\dfrac{2}{11}\)

\(\Rightarrow x+\dfrac{2}{3}=\dfrac{2}{11}-\dfrac{1}{11}\)

\(\Rightarrow x+\dfrac{2}{3}=\dfrac{1}{11}\)

\(\Rightarrow x=\dfrac{1}{11}-\dfrac{2}{3}\)

\(\Rightarrow x=-\dfrac{19}{33}\)

a,= 6-55-55-33+(-9)+(-6).11+22

= 6-(-33)+(-9)+(-66)+22

= 39+(-9)+(-66)+22

= 30+(-44)

= -14

b,= a+(-b)+(-c)+b+(-a)+c+(-c)+b

=[a+(-a)]+[(-b)+b+b]+[-c+c]

= 0+b+0

=b

11 - 12 = - 11

55 - 33 = 22

Hok tốt

11 - 22 = -11

55 - 33 = 22

11+22+33+44+55+66+77+88+99=495 nhé.

11 + 22 + 33 + 44 + 55 + 66 + 77 +88 + 99

= ( 11 + 99 ) + ( 88 + 22 ) + ( 33 + 77 ) + ( 44 + 66 ) + 55

= 100 + 100 + 100 + 100 + 55

= 100 x 4 + 55

= 400 + 55

= 455

11=1 vi 1=11

11=211

55=25125 vì

ta thấy 11=11 do 1 x1 =1 sau đó nhân tiếp

22=48 do 2 x2=4 nhân tiếp

55 = 25125 vì

Ta có : 1 x 1 = 1 ; 1 x 1 = 1 ; => 11 = 11

2 x 2 = 4 ; 4 x 2 = 8 ; => 22 = 48

Và 5 x 5 = 25 ; 25 x 5 = 125 ; => 55 = 25125
