Question

determine o valor das equações
{ (5² -2/3) +(45:5)}-10

Answer 1

{ (5² -2/3) +(45:5)}-10=
{ (25 -2/3) +(9)}-10=
(24 1/3 + 9) - 10 =
33 1/3 - 10 =
23 1/3

Answer 2

$( (5^2 - \frac{2}{3} ) +(45:5))-10$
$( (25 - \frac{2}{3} ) +9)-10$
$( ( \frac{75}{3} - \frac{2}{3} ) +9)-10$
$( \frac{73}{3} +9)-10$
$( \frac{73}{3} + \frac{27}{3} )-10$
$\frac{100}{3}-10$
$\frac{100}{3} - \frac{30}{3}$
$\frac{70}{3}$ ≈ 23,33...
