解:(1)4620+(401-438÷73),
=4620+(401-6),
=4620+395,
=5015;
(2)168-52-48,
=168-(52+48),
=168-100,
=68;
(3)1300÷25÷4,
=1300÷(25×4),
=1300÷100,
=13;
(4)37+125+63+175,
=(37+63)+(125+175),
=100+300,
=400;
(5)28×37+73×37-37,
=37×(28+73-1),
=37×100,
=3700;
(6)(300-1456÷26)×32,
=(300-56)×32,
=244×32,
=7808;
(7)8×(29×l25),
=(8×125)×29,
=1000×29,
=29000;
(8)99×l0l,
=99×(100+1),
=99×100+99×1,
=9900+99,
=9999.
分析:(1)先算小括号里面的除法,再算小括号里面的减法,最后算括号外的加法;
(2)根据连续减去两个数等于减去两个数的和简算;
(3)根据连续除以两个数等于除以这两个数的积;
(4)运用加法结合律简算;
(5)运用乘法分配律简算;
(6)先算小括号里面的除法,再算小括号里面的减法,最后算括号外的乘法;
(7)运用乘法交换律简算;
(8)运用乘法分配律简算.
点评:考查了运算定律与简便运算,四则混合运算.注意运算顺序和运算法则,灵活运用所学的运算律简便计算.
