Ответ:

3,2²:(-8/5)-13/5 = -(16/5)²×5/8-13/5 = -256/25×5/8-13/5 = -32/5-13/5 = -9

Пошаговое объяснение:

[tex]3.2 {}^{2} \div ( - \frac{8}{5} ) - \frac{13}{5} = - ( \frac{16}{5} ) {}^{2} \times \frac{5}{8} - \frac{13}{5 } = \frac{ - 256}{25} \times \frac{5}{8} - \frac{13}{5} = \frac{ - 32}{5} = 9 [/tex]

Verified answer

[tex]( - 3.2) {}^{2} \div (- 1.6) - 2 \frac{3}{5} = - 9\\ 1) \: ( - 3.2) {}^{2} = 10.24 \\ 2) \: 10.24 \div ( - 1.6) = - 6.4 \\3 ) \: - 6.4 - 2 \frac{3}{5} = - 6.4 - 2.6 = - 9[/tex]
