11 x 11 = ( 1 + 1 ) x ( 1 + 1 ) = 2 x 2 = 4
22 x 22 = ( 2 + 2 ) x ( 2 + 2 ) = 4 x 4 = 16
33 x 33 = ( 3 + 3 ) x ( 3 + 3 ) = 6 x 6 = 36
Đáp án 1 : 36
11 x11 = ( 1 + 1 ) x ( 1 + 1 ) = 2 x 2 = 4
22 x 22 = ( 2 + 2 ) x ( 2 + 2 ) = 4 x 4 = 16
33 x 33 = ( 3 + 3 ) x ( 3 + 3 ) = 6 x 6 =36
Đáp án 2 : 28
11 x 11 = 11 + ( 1 + 1 ) - 9 = 4
22 x 22 = 22 + ( 2 + 2 ) - 10 = 16
33 x 33 = 33 + ( 3 + 3 ) - 11 = 28

A = ( 15/22 - 2/22 ) : 1/33 - ( 6/84 - 8/84) : 1/35 + 1 + 1/5 . ( 3/12 - 2/12 - 12/12 ) . 5/11
A = 13/22 . 33 - (-1/42) . 35 + 1 + 1/5 . - 11/12 . 5/11
A = 39/2 - ( -5/6 ) + 1 + - 11/60 .5/11
A = 39/2 + 5/6 + 1 + (- 1/12)
A = 234/12 + 10 /12 + 12/12 + (-1/12)
A = 255/12

11 + 22 + ( \(x\) x 2 + \(x\) x 199 ) : 33 = 123 x 123
33 + \(x\) ( 2 + 199) : 33 = 15129
201\(x\) : 33 = 15129 - 33
201\(x\) : 33 = 15096
201\(x\) = 15096 x 33
201\(x\) = 498168
\(x\) = 498168 : 201
\(x\) = 166056/67

1: \(\dfrac{4}{23}+\dfrac{5}{21}+\dfrac{1}{2}-\dfrac{4}{23}+\dfrac{16}{21}\)
\(=1+\dfrac{1}{2}\)
\(=\dfrac{3}{2}\)
2: \(\left(\dfrac{1}{3}+\dfrac{12}{67}+\dfrac{13}{41}\right)-\left(\dfrac{79}{67}-\dfrac{28}{41}\right)\)
\(=\dfrac{1}{3}+\dfrac{12}{67}+\dfrac{13}{41}-\dfrac{79}{67}+\dfrac{28}{41}\)
\(=\dfrac{1}{3}\)
\(\dfrac{-7}{11}=\dfrac{x}{22}\Rightarrow\dfrac{-14}{22}=\dfrac{x}{22}\Rightarrow x=-14\)
\(\dfrac{-5}{11}=\dfrac{x}{33}\Rightarrow\dfrac{-15}{33}=\dfrac{x}{33}\Rightarrow x=-15\)
\(\dfrac{-7}{11}\)=\(\dfrac{x}{22}\)\(\Rightarrow\)11x=-7.22\(\Rightarrow\)11x=-154\(\Rightarrow\)x=-154:11=-14
\(\dfrac{-5}{11}\)=\(\dfrac{x}{33}\)\(\Rightarrow\)11x=-5.33\(\Rightarrow\)11x=-165\(\Rightarrow\)x=-165:11=-15
