原式=3x11.5x3x0.6x3x0.9
=27x11.5x0.54
=27x10x0.54+27x1.5x0.54
=270x0.54+27x0.54+27x0.5x0.54
=27x(5.4+0.54)+27x0.27
=27x(5.94+0.27)
=27x6.21
=27x6+27x0.2+0.27
=162+5.4+0.27
=167.67
=27x11.5x0.54
=27x10x0.54+27x1.5x0.54
=270x0.54+27x0.54+27x0.5x0.54
=27x(5.4+0.54)+27x0.27
=27x(5.94+0.27)
=27x6.21
=27x6+27x0.2+0.27
=162+5.4+0.27
=167.67
