To solve this question you would plug in the values given into the expression making sure that you include any negative signs and obey order of operations. The expression 8x(yz-1) would become 8(-2) ((-3)(5)-1).
(-3)(5)=-15, so the expression would change to 8(-2)(-15-1).
 
-15-1=-16
8(-2)=-16
-16*-16=256
