3.51*49+35.1*5.1+49*5.1
3.51*49+35.1*5.1+49*5.1
=3.51×49+3.51×51+49×5.1
=3.51×(49+51)+49×5.1
=351+49×49(5+0.1)=351+245+4.9=600.9

3.51*49+35.1*5.1+49*5.1
=3.51×49+3.51×51+49×5.1
=3.51×(49+51)+49×5.1
=351+49×49(5+0.1)=351+245+4.9=600.9

600.9

3.51*49+3.51*51+49*5.1= 3.51*(49+51)+49*5.1=351+49*5.1=351+249.9=600.9
