Question

Es de matemáticas es hasta mañana me pueden ayudar tiene que estar resuelto con su proseco

Answer 1

Respuesta:

1)

$\frac{3}{2}+\left(\frac{1}{4}\left(\frac{7}{2}-\frac{6}{4}\right)\right)^3\\\\\\\frac{3}{2}+\frac{1}{2^3}\\\\\\\frac{3}{2}+\frac{1}{8}\\\\\\\frac{12}{8}+\frac{1}{8}\\\\\\\frac{12+1}{8}\\\\\\Rpta=\frac{13}{8}$

2)

$\frac{2}{5}-\left(\left(\frac{2}{5}+\frac{3}{5}\right)^2\div \frac{5}{7}\right)\\\\\\1^2\div \frac{5}{7}\\\\\\1\div \frac{5}{7}\\\\\\\frac{7}{5}\\\\\\\frac{2}{5}-\frac{7}{5}\\\\\\\frac{2-7}{5}\\\\\\\frac{-5}{5}\\\\\\-\frac{5}{5}\\\\\\Rpta=-1$

3)

$\left(\frac{10}{15}\left(\frac{2}{4}+\frac{3}{8}\right)\right)^2-\frac{1}{10}\\\\\\\frac{7^2}{12^2}-\frac{1}{10}\\\\\\\frac{49}{144}-\frac{1}{10}\\\\\\\frac{245}{720}-\frac{72}{720}\\\\\\\frac{245-72}{720}\\\\\\\frac{173}{720}$

4)

$\left(\frac{4}{5}+\frac{3}{10}-\frac{2}{5}\cdot \frac{15}{4}\right)^3\\\\\\\left(\frac{4}{5}+\frac{3}{10}-\frac{3}{2}\right)^3\\\\\\\left(-\frac{2}{5}\right)^3\\\\\\-\left(\frac{2}{5}\right)^3\\\\\\-\frac{2^3}{5^3}\\\\\\-\frac{8}{5^3}\\\\\\-\frac{8}{125}$

Las formulas que use <3...

$\frac{a}{c}\pm \frac{b}{c}=\frac{a\pm \:b}{c}$

$\left(-a\right)^n=a^n,\:\mathrm{si\:}n\mathrm{\:es\:impar}$

$\left(\frac{a}{b}\right)^c=\frac{a^c}{b^c}$
