AAAA+BBB+CC+D=2002求A.B.C.D是多少?

AAAA+BBB+CC+D=2002求A.B.C.D是多少? AAAA+BBB+CC+D=2002求A.B.C.D是多少? AAAA乘以B-BBB=3000,那么A乘以B=? 已知aa+bb+cc-2（a+b+c）+3=0,求aaa+bbb+ccc-3abc的值 AAAA - BBB __________2BB7 aa=bbb bbb=cccc a+b+cc=400.a=?b=?c=? AA=BBB BBB=CCCC A+B+CC=80 A=( ) B=( ) C=( ) AA=BBB BBB=CCCC A+B+CC=80 A=( ) B=( ) C=( ) 在MATLAB里用数值画的曲线怎么求其交点值并让其值在图上显示出来AA=mean(A);BB=mean(B);CC=mean(C);AAA=std(A);BBB=std(B);CCC=std(C);AAAA=sort(A);BBBB=sort(B);CCCC=sort(C);plot(AAAA,normpdf(AAAA,AA,AAA),'r');hold on ;plot(BBBB,nor A*B*AB=BBB求A和B 己知a×b×ab=bbb,求a×b AAA+BBB=1BBB 请问 A,B 是多少? 1/(a-b)-1/(a+b)-2b/(aa+bb)-4bbb/(aaaa+bbbb)+8bbbbbbb/(bbbbbbbb-aaaaaaaa) 怎么证明2(aaa+bbb+ccc)>aa(b+c)+bb(a+c)+cc(a+b) (aaa/aa+ab+bb)+(bbb/bb+bc+cc)+(ccc/cc+ca+aa)≥ (a+b+c)/3 (aaa/aa+ab+bb)+(bbb/bb+bc+cc)+(ccc/cc+ca+aa)≥ (a+b+c)/3如何证明? matlab高手看看怎么求这个函数的最大值dy =0.000099261901556999720041760126854058*bbb^5 - 0.0023305907031025767622671451828609*bbb^4 - 0.025259643140202740069222286933837*bbb^3 + 0.81623253924995070596182245026284*bbb^2 - 3.66326010440757 AAA+AAA=1BBB,求A B分别等于多少?
