解：(1)56*18-504/36 =56*18-56*9/36=56*(18-1/4)=56*18-14=71*14=994；
(2)75+（52-36）*18=75+16*18=3*(25+96)=3*121=363。
56×9×2－504／36
=56*9*2-(3*2*2*2*3*7)/(2*2*3*3)
=56*9*2-2*7
=8*7*9*2-14
=8*7*2*(10-1)-14
=1120-112-14
=1008-14
=994
75+（52-36）*18
=3*5*5+16*3*6
=3*(25+4*4*6)
=3*[25+4*(25-1)]
=3*100+3*(25-4)
=363
希望采纳，谢谢！
