3.8×5.46+7.2×5.46-5.46
=5.46×(3.8+7.2-1)
=5.46×10
=54.6;
4.6×2.02
=4.6×(2+0.02)
=9.2+0.092
=9.292
3.8×5.46+7.2×5.46-5.46
=5.46X(3.8+7.2-1)
=5.46X10
=54.6
4.6×2.02
=4.6X(2+0.02)
=4.6X2+4.6X0.02
=9.2+0.092
=9.292
3.8×5.46+7.2×5.46-5.46
=5.46(3.8+7.2-1)
=5.46*10
=54.6
4.6×2.02
=4.6*2*(1+0.01)
=9.2+0.092
