解：解：根据已知条件，计算：
0.62x3.2+6.2x0.32
=0.62x10x3.2÷10+6.2x0.32
=6.2x0.32+6.2x0.32
=6.2x(0.32+0.32)
=6.2x0.64
=6.2x8x0.08
=49.6x0.08

根据题意可得:
0.62x3.2+6.2x0.32
=0.62x3.2+6.2÷10x0.32
=0.62x3.2+0.62x0.32
=2x0.62x3.2
=1.24x3.2
=(1.25-0.01)x3.2
=1.25x3.2-0.01x3.2
=1.25x8x0.4-0.01x3.2
=4-0.032
=3.968
0.62x3.2+6.2x0.32
=0.62x3.2+6.2÷10x0.32
=0.62x3.2+0.62x0.32
=2x0.62x3.2
=1.24x3.2
=(1.25-0.01)x3.2
=1.25x3.2-0.01x3.2
=1.25x8x0.4-0.01x3.2
=4-0.032
=3.968

0.62*3.2+6.2*0.32
=3.2*0.62+3.2*0.62
=3.2*（0.62+0.62）
=3.2*1.24
=3.968
=3.2*0.62+3.2*0.62
=3.2*（0.62+0.62）
=3.2*1.24
=3.968

解：依题意得
0.62×3.2+6.2×0.32
=6.2×0.1×3.2+6.2×0.32
=6.2×（0.32+0.32）
=6.2×（0.6+0.04）
=6.2×0.6+6.2×0.04
=3.968
