me ayudan con Matemática por favor​

Answer 1

Respuesta:

$1) \\ \sqrt[3]{ {5}^{2} + 2 } + (5 \times 3 - 3)^{2} \div {3}^{2} - {7}^{0} \\ \sqrt[3]{25 + 2} + (15 - 3)^{2} \div 9 - 1 \\ \sqrt[3]{27} + {12}^{2} \div 9 - 1 \\ 3 + 144 \div 9 - 1 \\ 3 + 16 - 1 \\ 19 - 1 = 18$

$2) \: a) \\ \frac{3}{5} + \frac{14}{5} \div \frac{5}{2} = \\ \\ \frac{3}{5} + \frac{28}{25} = \frac{15 + 28}{25} = \frac{43}{25}$

$b) \\ \frac{3}{4} + \frac{1}{2} - \frac{3}{8} = \frac{6 + 4 - 3}{8} = \frac{7}{8}$

$c) \\ \frac{18}{5} - \frac{3}{2} + \frac{2}{5} = \\ \\ \frac{36 - 15 + 4}{10} = \frac{25}{10} = \frac{5}{2}$

$d) \\ \frac{8}{4} \times \frac{27}{20} = \frac{216}{80} = \frac{27}{10}$
