\[\boxed{\text{25\ (25).}\text{\ }\text{Еуроки\ -\ ДЗ\ без\ мороки}}\]
Пояснение.
Решение.
\[a\] | \[5\] | \[- 2\] | \[4\] | \[1\] | \[6\] |
---|---|---|---|---|---|
\[b\] | \[- 3\] | \[3\] | \[0\] | \[- 1\] | \[4\] |
\[a - 2b\] | \[11\] | \[- 8\] | \[4\] | \[3\] | \[- 2\] |
\[5\ - \ 2\ \cdot \ ( - 3) = \ 5\ + \ 6\ = \ 11\]
\[- 2\ - \ 2\ \cdot \ 3\ = \ - 2\ - \ 6\ = \ - 8\]
\[4\ - \ 2\ \cdot \ 0\ = \ 4\ - \ 0\ = \ 4\]
\[1\ - \ 2\ \cdot \ ( - 1) = \ 1\ + \ 2\ = \ 3\]
\[6\ - \ 2\ \cdot \ 4\ = \ 6\ - \ 8\ =\]
\[= - (8 - 6) = \ - 2\]
