Answer

Finally, we get the result as $32$

Steps

Step 1 ：Given the algebraic expression $x^{2}-8(x-y)$, where $x=8$ and $y=4$

Step 2 ：Substitute the given values of x and y into the expression, which gives $8^{2}-8(8-4)$

Step 3 ：Simplify the expression to get $64-8*4$

Step 4 ：Further simplify to get $64-32$

Step 5 ：Finally, we get the result as $32$
