3.42乘76.3加57.6乘7.63加91.8乘2.3.7
=7.63x(34.2+57.6)+91.8x2.37
=7.63x91.8+91.8x2.37
=(7.63+2.37)x91.8
=10x91.8
=918
2.3.7是什么啊?
=260.946+439.488+217.566=918
3.42*76.3+57.6*7.63+91.8*2.37
=34.2*7.63+57.6*7.63+91.8*2.37
=(34.2+57.6)*7.63+91.8*2.37
=91.8*7.63+91.8*2.37
=91.8*(7.63+2.37)
=91.8*10
=918
3.42×76.3 + 57.6×7.63 + 91.8×2.37
= 34.2×7.63 + 57.6×7.63 + 91.8×2.37
= (34.2 + 57.6)×7.63 + 91.8×2.37
= 91.8×7.63 + 91.8×2.37
= 91.8×(7.63 + 2.37)
= 91.8×10
= 918
3.42*76.3+57.6*7.63+91.8*2.37
=7.63*(34.2+57.6)+91.8*2.37
=7.63*91.8+91.8*2.37
=(7.63+2.37)*91.8
=918
