Răspuns:

Explicație pas cu pas:

$\bf \big [\big(5^5 \cdot5^{20}\big):5^{22}-5^{2}:5\big]\cdot2^{3}=$

$\bf \big [\big(5^{5+20}\big):5^{22}-5^{2}:5^1\big]\cdot2^{3}=$

$\bf \big(5^{25}:5^{22}-5^{2-1}\big)\cdot2^{3}=$

$\bf \big(5^{25-22}-5^{1}\big)\cdot2^{3}=\big(5^{3}-5^{1}\big)\cdot2^{3}=$

$\bf 5\cdot\big(5^{3-1}-5^{1-1}\big)\cdot2^{3}=$

$\bf 5\cdot\big(5^{2}-5^{0}\big)\cdot2^{3}=$

$\bf 5\cdot\big(25-1\big)\cdot2^{3}=$

$\bf 5\cdot 24 \cdot8 =\red{\underline{~960~}}$
