\(\left|\frac{-12}{7}\right|.\frac{-34}{9}\)

= \(\frac{12}{7}.\frac{-34}{9}\)

= \(\frac{4.\left(-2\right)}{1.1}\)

= \(-8\)

\(\left|\frac{-12}{17}\right|.\left(\frac{-34}{9}\right)\)

= \(\frac{12}{17}.\left(\frac{-34}{9}\right)\)

= \(\frac{4.\left(-2\right)}{1.1}\)

= \(-8\)

\(\left|\frac{-12}{17}\right|.\left(\frac{-34}{9}\right)\)

= \(\frac{12}{17}.\left(\frac{-34}{9}\right)\)

= \(\frac{4.\left(-2\right)}{1.3}\)

= \(\frac{-8}{3}\)

14+6= 20

15+5= 20

17+6= 23

123456+12= 123468

14+6=20

15+5=20

17+6=23

123456+12=1234568

14 + 6 = 20

15 + 5 = 20

17 + 6 = 23

123456 + 12 = 123468

chúc vui vẻ

Kết quả đúng rồi đó
