答案

(1)17×25×8,

=17×25×4×2,

=17×2×(25×4),

=34×100,

=3400;

(2)73×18+82×73,

=73×(18+82),

=73×100,

=7300;

(3)6756-193-207,

=6756-(193+207),

=6756-400,

=6356;

(4)183-25-75+117,

=183+117-(25+75),

=300-100,

=200;

(5)64×101,

=64×(100+1),

=6400+64,

=6464;

(6)326×124-326×24,

=326×(124-24),

=326×100,
