5.4×4.6+0.54×5
=5.4*4.6+5.4*5/10
=5.4*(4.6+0.5)
=5.4*5.1
=(5+0.4)*(5+0.1)
=5*5+0.4*0.1+0.4*5+5*0.1
=25+0.04+2+0.5
=27.54
=5.4*4.6+5.4*5/10
=5.4*(4.6+0.5)
=5.4*5.1
=(5+0.4)*(5+0.1)
=5*5+0.4*0.1+0.4*5+5*0.1
=25+0.04+2+0.5
=27.54

5.4×4.6+0.54×5
=5.4×4.6+5.4×0.5
=5.4×(4.6+0.5)
=5.4×5.1
=5.4×(5+0.1)
=5.4×5+5.4×0.1
=27+0.54
=27.54
=5.4×4.6+5.4×0.5
=5.4×(4.6+0.5)
=5.4×5.1
=5.4×(5+0.1)
=5.4×5+5.4×0.1
=27+0.54
=27.54
