分析:(1)(6)运用乘法分配律简算;
(2)运用乘法交换律和结合律简算;
(3)运用乘法交换律简算;
(4)先根据积不变规律,把33×33变成99×3,再运用乘法分配律简算,然后再把99分解成(100-1),再次运用乘法分配律简算;
(5)根据除法的性质简算.
解答:解:(1)27×48+27×52,
=27×(48+52),
=27×100,
=2700;
(2)125×25×4×8,
=(125×8)×(25×4),
=1000×100,
=100000;
(3)125×(296×80),
=125×80×296,
=10000×296,
=2960000;
(4)33×33+99×89,
=99×3+99×89,
=99×(3+89),
=99×92,
=(100-1)×92,
=100×92-1×92,
=9200-92,
=9108;
(5)560÷7÷8,
=560÷(7×8),
=560÷56,
=10;
(6)88×201-88,
=88×(201-1),
=88×200,
=17600.
