Question

(3supra5 × 2+5+3supra5):(-3)totul supra 5​

Answer 1

Explicație pas cu pas:

$\frac{ (\frac{3}{5} \times 2 + 5 + \frac{3}{5}) \div ( - 3)}{5} = \frac{ \frac{6}{5} + \frac{25}{5} + \frac{3}{5}}{ - 3 \times 5} = \frac{ \frac{6 + 25 + 3}{5} }{ -15} = \frac{34}{ - 15 \times 5} = - \frac{34}{75}$

$(\frac{3}{5} \times 2 + 5 + \frac{3}{5}) \div (-3)^{5} = (\frac{6}{5} + \frac{25}{5} + \frac{3}{5})÷(-3^{5}) = -(\frac{6 + 25 + 3}{5})÷(3^{5})=-(\frac{34}{5})÷(243)=-\frac{34}{5×243}=-\frac{34}{1215}$
