35×(21﹢480÷32);
〔368-(132+129)〕×34;
125×5×8×2;
(736÷16﹢27)×5.
答案
(1)153×43﹢43×47,
=(153+47)×43,
=200×43,
=8600;
(2)101×16,
=(100+1)×16,
=100×16+16,
=1600+16,
=1616;
(3)35×(21﹢480÷32),
=35×(21+15),
=35×36,
=1260;
(4)〔368-(132+129)〕×34,
=[368-261]×34,
=107×34,
=(100+7)×34,
=100×7+7×34,
=700+238,
=938;
(5)125×5×8×2,
=125×8×(5×2),
=1000×10,
=10000;
(6)(736÷16﹢27)×5,
=(46+27)×5,
=365.
