See a solution process below:

For each of occurrence of $s$ $color(red)(s)$ in the expression substitute $7$ $color(red)(7)$

For this problem the variables $a$ $a$ and $m$ $m$ and $t$ $t$ are extraneous or not used and therefore not needed.

$(s + 1) (s^{2} - s + 1)$ $(color(red)(s) + 1)(color(red)(s)^2 - color(red)(s) + 1)$ becomes:

$(7 + 1) (7^{2} - 7 + 1) \Rightarrow$ $(color(red)(7) + 1)(color(red)(7)^2 - color(red)(7) + 1) =>$

$8 (49 - 7 + 1) \Rightarrow$ $8(49 - color(red)(7) + 1) =>$

$8 \cdot 43 \Rightarrow$ $8 * 43 =>$

$344$ $344$
