Answer 1

Răspuns: $\color{red}\Large\boxed{ \bf -2567}$

Explicație pas cu pas:

$\large \bf 300 - 4\cdot\{ 18 +(-3)\cdot[20 -5\cdot ( 25 -(-3)^{3})] - 3^{2}\} + [(-7)^{3}]^{5} : ( -7)^{13} =$

$\large \bf 300 - 4\cdot\{ 18 -3\cdot[20 -5\cdot ( 25 -(-27)] - 9\} + (-7)^{3\cdot5} : ( -7)^{13} =$

$\large \bf 300 - 4\cdot\{ 18 -3\cdot[20 -5\cdot ( 25 +27)] - 9\} + (-7)^{15} : ( -7)^{13} =$

$\large \bf 300 - 4\cdot\{ 18 -3\cdot[20 -5\cdot 52] - 9\} + (-7)^{15-13} =$

$\large \bf 300 - 4\cdot\{ 18 -3\cdot[20 -260] - 9\} + (-7)^{2} =$

$\large \bf 300 - 4\cdot[18 -3\cdot(-240) - 9] + 49=$

$\large \bf 300 - 4\cdot[18 +720 - 9] + 49=$

$\large \bf 300 - 4\cdot 729+ 49=$

$\large \bf 300 - 2916+ 49=$

$\color{red}\Large\boxed{ \bf -2567}$
