Answer 2

原式=（4.5+0.3）*5.2+4.5*1.8
=0.3*5.2+4.5*（5.2+1.8）
=15.6+4.5*7
=15.6+31.5
=47.1

Answer 3

Answer 4

（4.5+0.3）×5.2+4.5×1.8
=4.5×5.2+0.3×5.2+4.5×1.8
=4.5×（5.2+1.8）+0.3×5.2
=4.5×7+1.56
=31.5+1.56
=33.06

Answer 5

4.8×5.2+4.5×1.8
=4.8×(5+.02)+4.5×(2－0.2)
=4.8×5+4.8×0.2+4.5×2－4.5×0.2
=24+0.96+9－0.9
=33.06
