c123
都是3的倍数阿
VBA 代码 a=$A$10,$A$14,$A$18,$A$12,$A$12,$A$14,$A$18,$A$10变量a为下面的形式,其中的元素可能很多a=$A$10,$A$14,$A$18,$A$12,$A$15,$A$14,$A$18,$A$11如果有重复的例如其中有2个$A$14和2个$A$18则将这4个元素连同其
23-a-{10a-[(5a-15)-(4-6a)]}
请问,这17道关于一元一次方程的题目我做对了吗?(1)A-5=6A-5+5=6+5A=11(2)0.3A=45A=13.5(3)5A+4=05A=4A=0.8(4)5A-2A=93A=9A=3(5)-3A+0.5A=10-2.5A=10A=4(6)6A-4=4A-56A-4A=-5+42A=-1A=0.5(7)2A+3A+4A=189A=18A=2(8)13A-15A+A=-3-3A=-3A=1(9)
18a^2-{-6a^2+[5a-4a^2-(a^2-2a)]+15a^2-5a},其中a=-1/6
18a^2-{-6a^2+[5a-4a^2-(a^2-2a)]+15a^2-5a},其中a=-1/6
充电器上5A 10A 15A
因式分解15a立方+10A平方
15a^3+10a^2
15a^3+10a^2
LINGO错误,这段程序为什么会出现以下错误:程序:clc;clear;M=1000;a(1,2)=8; a(1,3)=5;a(1,4)=9;a(1,5)=12;a(1,6)=14;a(1,7)=12;a(1,8)=16;a(1,9)=17;a(1,10)=22;a(2,3)=9; a(2,4)=15;a(2,5)=17;a(2,6)=8;a(2,7)=11;a(2,8)=18;a(2,9)=14;a(2,10)=22;
下列计算正确的是( )A .a^5-a^3=a^2 B.a^5*a^3=a^15 C.4^6/a^3=a^2 D.(-a^5)^2=a^10
因式分解:2a^b^2+10a^2b+12a^2-3ab^2-15ab-18a-b^2-5b-6Quickly!(主元法)
逻辑运算中A表示什么 (1) 0 · A = 0 (10) 1' = 0; 0' = 1 (2) 1 · A = A (11) 1 + A = 1 (3) A · A = A (12) 0 + A = A (4) A · A' = 0 (13) A + A = A (5) A · B = B · A (14) A + A' = 1 (6) A·(B·C) = (A·B)·C (15) A

试证明代数式-(a-23)-{10a-[5a-15-(4-6a)]}
a+b+c=10 a+a+b=12 a+b+c+c=15
若a+1/a=5,则3a^-15a+10=?
