4/5 x4+2/5x2+1/5x16 简便计算
4/5 x4+2/5x2+1/5x16 简便计算
4/5 x4+2/5x2+1/5x16
=16*1/5+4*1/5+16*1/5
=1/5(16+4+16)
=1/5*36
=36/5
=7.2
百度知道有,真的
呃

六年级4/5x4+2/5x2+5/1x16怎么算啊?
1x2+2x3+3x4+4x5+.+15x16
1x2+2x3+3x4+4x5...+15x16,结果是奇数还是偶数?
请你认真观察下面各个式子,然后根据你发现的规律写出第4,5个式子√16=√1x16=√1x4²=√1x√4²=1x4=42.√32=√2x16=√2x4²=√2x√4²=√2x4=4√23.√48=√3x16=√3x4²=√3x√4²=√3x4=4√3

确定a的值,使线性方程组{X1+X2+X3+X4=1,3X1+2X2+X5+X4=0,X2+2X3+2X4=a,5X1+4X2+3X2+3X4=2 并求通解
非齐次线性方程组求解.x1+x2+2x3+3x4=1 2x1+3x2+5x3+2x4=-3 3x1-x2-x3-2x4=-4 3x1+5x2+2x3-2x4=-10
讨论2X1+X2-X3+X4=1 3X1-2X2+2X3-3X4=2 5X1+X2-X3+2X4=-1 2X1-X2+X3-3X4=4的解的情况
求非齐次线性方程组的通解x1+3x2+5x3-4x4=1x1+3x2+2x3-2x4+x5=-1x1-2x2+x3-x4-x5=3x1+2x2+x3-x4-x5=3
x1-x2+x3=1 x2-x3+x4=2 x3-x4+x5=3 x4-x5+x1=4 x5-x1+x2=5 求x1,x2,x3,x4,x5
下列方程组如何解 2x1+x2-2x3+3x4=1 3x1+2x2-x3+2x4=4 3x1+3x2+3x3-3x4=52x1+x2-2x3+3x4=13x1+2x2-x3+2x4=43x1+3x2+3x3-3x4=5如何解这个线性方程组,因为不太懂。
若x1,x2,x3,x4,x5满足方程组:x1-x2+x3=1 x2-x3+x4=2 x3-x4+x5=3 x4-x5+x1=4 x5-x1+x2=5 求x2,x3,x4的少打了个字,是求x2,x3,x4的值
