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.
