一道方程,在问题补充哪儿.
1.11×327327×125-3×125125×327=?(简算)
2.12345×12346-12344×12343=?(简算)
3.(12-4x)×2=12-3x=?(方程)
1.11×327327×125-3×125125×327=?(简算)
2.12345×12346-12344×12343=?(简算)
3.(12-4x)×2=12-3x=?(方程)
11×327327×125-3×125125×327
=11*1001*327*125-3*125*1001*327
=1001*327*125(11-3)
=1001*327*125*8
=327327000
12345×12346-12344×12343
=(12344+2)×(12343+2)-12344×12343
=2(12343+12344)+4
=2(12344+12345)
=2*24690-2
=49378
(12-4x)*2=12-3x
24-8x=12-3x
5x=12
x=12/5=2.4
=11*1001*327*125-3*125*1001*327
