Question 365706
{{{bc^3-ad}}} Start with the given expression.



{{{(3)(-4)^3-(-2)(4)}}} Plug in a=-2,b=3,c=-4,and d=4



{{{(3)(-64)-(-2)(4)}}} Cube -4 to get -64



{{{-192-(-8)}}} Multiply



{{{-192+8}}} Rewrite {{{-192-(-8)}}} as {{{-192+8}}}



{{{-184}}} Add



So {{{bc^3-ad=-184}}} when a=-2,b=3,c=-4,and d=4
