Cine mi-l rezolva asta, ii iubit tare tate de Dumnezeu

Answer 1

Explicație pas cu pas:

$x + 3 \cdot ( {3}^{2016} \cdot 3 + {3}^{2017} + {3}^{2018}) = 3 \cdot {3}^{2019}$

$x + 3 \cdot ( {3}^{2017} + {3}^{2017} + {3}^{2018}) = {3}^{2020}$

$x + 3 \cdot {3}^{2017} \cdot (1 + 1 + 3) = {3}^{2020}$

$x + {3}^{2018} \cdot 5 = {3}^{2020}$

$x = {3}^{2020} - 5 \cdot {3}^{2018}$

$x = {3}^{2018} \cdot ( {3}^{2} - 5)$

$x = {3}^{2018} \cdot ( 9 - 5)$

$x = 4 \cdot {3}^{2018}$
