分析:(1)根据乘法结合律进行计算;
(2)16=4×4,再根据乘法交换律和结合律进行计算;
(3)先算小括号里面的乘法,再算括号外面的乘法;
(4)88=8×11,再根据乘法结合律进行计算;
(5)先算小括号里面的乘法,再算括号外面的乘法;
(6)先算小括号里面的乘法,再算括号外面的乘法.
解答:解:
(1)16×(5×9),
=(16×5)×9,
=80×9,
=720;
(2)15×25×16,
=15×25×(4×4),
=(15×4)×(25×4),
=60×100,
=6000;
(3)(125×8)×11,
=1000×11,
=11000;
(4)125×88,
=125×(8×11),
=(125×8)×11,
=1000×11,
=11000;
(5)(16×5)×9,
=80×9,
=720;
(6)(15×4)×(25×4),
=60×100,
=6000;
所以,
.
