908×501-[731×1389-(547×236+842×731-495×361)]=______
答案
原式=908×501-731×1389+(547×236+842×731-495×361)
=908×501-731×1389+547×236+842×731-495×361
=908×501-731×+547×236-495×361
=908×501-731×547+547×236-495×361
=908×501-(731-236)×547-495×361
=908×501-495×547-495×361
=908×501-495×(547+361)
=908×501-495×908
=908×(501-495)
=908×6
=5448.
故本题答案为:5448.
