Answer 1

máy tính tính ra là : 

64.4

............

Answer 2

\(\frac{13}{2}\times\frac{27}{5}\times2\times\frac{34}{9}\times2\times\frac{2}{17}\)

\(=\frac{13\times27\times2\times34\times2\times2}{2\times5\times9\times17}\)

\(=\frac{95472}{1530}\)

\(=\frac{312}{5}=62,4\)

Answer 3

Kết quả = 3,9

Học tốt

Answer 4

\(\frac{13}{2}\times\frac{27}{5}\times2\times\frac{34}{9}\times2\times\frac{2}{17}\)

\(=\frac{13\times27\times2\times34\times2\times2}{2\times5\times1\times9\times1\times17}\)

\(=\frac{13\times3\times9\times2\times2\times17\times2\times2}{2\times5\times1\times9\times1\times17}\)

\(=\frac{13\times3\times2\times2\times2}{5\times1\times1}=\frac{312}{5}\)

Answer 6

\(\frac{13}{2}\times\frac{27}{5}\times2\times\frac{34}{9}\times2\times\frac{2}{17}\)

\(=\frac{13}{2}\times\frac{27}{5}\times\frac{2}{1}\times\frac{34}{9}\times\frac{2}{1}\times\frac{2}{17}\)

\(=\frac{13\times27\times2\times34\times2\times2}{2\times5\times1\times9\times1\times17}=\frac{13\times3\times9\times2\times2\times17\times2\times2}{2\times5\times1\times3\times3\times1\times17}=\frac{312}{5}=62,4\)
