(36 - 1²).(36 - 2²).(36 - 3²)...(36 - 20²)

= (36 - 1²).(36 - 2²)...(36 - 6²)...(36 - 20²)

= (36 - 1²).(36 - 2²)...(36 - 36)...(36 - 20²)

= (36 - 1²)(36 - 2²)...0...(36 - 20²)

= 0

36 x 2 + 36 x 5 + 3 x 36

= 36 x ( 2 + 3 + 5 )

= 36 x 10

= 360

=36×(2+5+3)

=36×10

=360

Do you remember me?

36 x 2 + 36 x 5 + 36 x 3

               = 36 x ( 2 + 3 + 5 )

               = 36 x 10

               = 360

Lấy máy tính bấm  nhé 

36(2+5+3)=36 x 10 = 360

Ta có: \(36^2+64^2+2\cdot36\cdot64=\left(36+64\right)^2=100^2=10000\)

35 x 36 + 36 x 63 + 36 : 1/2​

= 35 x 36 + 36 x 63 + 36 x 2

= 36 x ( 35 + 63 + 2 )

= 36 x 100

= 3 600

/HT\

=35x36+36x63+36x2 (nếu bn ko hiểu tại sao mik nhân 2 thì: 36 : 1/2 = 36 x 2/1= 36 x2) =35x(35+63+2) = 35x100=3500

=35 x 36 + 36 x 63 + 36 x 2
=36 x (35 + 63 +2)
=36 x 100
=3600

      \(36^2+24^2+36.48\)

\(=36^2+2.36.24+24^2\)

\(=\left(36+24\right)^2=60^2=3600\)

E = \(\frac{36}{1\cdot7}+\frac{36}{7\cdot13}+...+\frac{36}{94\cdot100}=\frac{36}{6}\left[\frac{1}{1\cdot7}+\frac{1}{7\cdot13}+...+\frac{1}{94\cdot100}\right]\)

\(=6\left[1-\frac{1}{7}+\frac{1}{7}-\frac{1}{13}+...+\frac{1}{94}-\frac{1}{100}\right]=6\left[1-\frac{1}{100}\right]\)

\(=6\cdot\frac{99}{100}=\frac{297}{50}\)

F = \(\frac{1}{10}+\frac{1}{40}+\frac{1}{88}+...+\frac{1}{\left[3a+2\right]\left[3a+5\right]}\)

\(=\frac{1}{2\cdot5}+\frac{1}{5\cdot8}+\frac{1}{8\cdot11}+...+\frac{1}{\left[3a+2\right]\left[3a+5\right]}\)

\(=\frac{1}{3}\left[\frac{1}{2}-\frac{1}{5}+\frac{1}{5}-\frac{1}{8}+\frac{1}{8}-\frac{1}{11}+...+\frac{1}{3a+2}-\frac{1}{3a+5}\right]\)

\(=\frac{1}{3}\left[\frac{1}{2}-\frac{1}{3a+5}\right]=\frac{1}{6}-\frac{1}{9a+15}\)

G = \(\frac{1}{2\cdot3}+\frac{2}{3\cdot5}+\frac{3}{5\cdot8}+\frac{4}{8\cdot12}+\frac{5}{12\cdot17}=\frac{1}{2}-\frac{1}{3}+\frac{1}{3}-\frac{1}{5}+...+\frac{1}{12}-\frac{1}{17}\)

\(=\frac{1}{2}-\frac{1}{17}=\frac{15}{34}\)

E=36/1-36/7+36/7-36/13+...+36/94-36/100

  =36-36/100=891/25

36/9 : 5/14 + 36/9 : 2/14

= 36/9 : ( 5/14 + 2/14) 

= 36/9 : 2/7

=252/18

   có j sai sót mong em bỏ qua nhé- tại chị học qua lâu rùi nên ko nhớ lăm!!!!!:3

sorry pé nhá

  36/9 : ( 5/14 + 2/14 )

= 36/9 : 7/14

( 36/9 = 4)

=4: 7/14

=56/7 

 nhá hồi nãy chị làm nhầm:)

toán mà sao nói là tiếng Anh
