Question

1 si 2 va rog..... ​

Answer 1

1)

${( - 2)}^{14} \div {( - 2)}^{12} = {( - 2)}^{2} = 4$

$\frac{2}{ \frac{4}{5} } = 2 \div \frac{4}{5} = 2 \times \frac{5}{4} = \frac{5}{2}$

2)

$\frac{x + 1}{3} = \frac{2}{3} \\ stim \: ca \: produsul \: \\ mezilor = produsul \: extremilor \\ 3(x + 1) = 6 \\ x + 1 = 2 \\ = 1$
