答案

(1)35×(26÷2+7),

=35×(13+7),

=35×20,

=700;

(2)400÷[480÷(16+8)],

=400÷[480÷24],

=400÷20,

=20;

(3)78×26+26×22,

=(78+22)×26,

=100×26,

=2600;

(4)57×101-57,

=57×(101-1),

=57×100,

=5700;

(5)125×(8+4),

=125×8+125×4,

=1000+500,

=1500;

(6)(86+19)×(95-69),

=105×26,

=(100+5)×26,

=100×26+5×26,
