解: 10.4×0.68+0.34×2×4.6
=10.4×0.68+0.68×4.6
=0.68x(10.4+4.6)
=0.68x15
=0.68x(10+5)
=6.8+3.4
=10.2
=10.4×0.68+0.68×4.6
=0.68x(10.4+4.6)
=0.68x15
=0.68x(10+5)
=6.8+3.4
=10.2

=0.68x（10.4+4.6）
=0.68x15
=10.2
=10.4x0.68+0.68x4.6
=0.68x（10.4+4.6）

10.4×0.68+0.34×2×4.6
=10.4×0.68+0.68×4.6
=(10.4+4.6)×0.68
=15×0.68
=30×0.34
=10.2
=10.4×0.68+0.68×4.6
=(10.4+4.6)×0.68
=15×0.68
=30×0.34
=10.2

=10.4*0.68+（0.34*2）*4.6
=10.4*0.68+0.68*4.6
=0.68*（10.4+4.6）
=0.68*15
=10.2
=10.4*0.68+0.68*4.6
=0.68*（10.4+4.6）
=0.68*15
=10.2
