(10a+b)+(10b+a)

(a-b)^10/(b-a)^4/(b-a)^8 A=10 B=20 A=A+B B=A-B A=A-B Print"A=";A,"B=";B a^2+b^2=100,a/10=b/(b+10)求解a,b printf("%d\n",i>5?10:100);b++;y=(a+b,a-b,a*b); a+b>a-b, (a-b)(a b) a/b-b/a 同底数幂乘方(a-b)^5*(a-b)^10*(b-a)(a-2b)^2*(a-2b)*4*(a-b)(x-3y)^2* 已知a=11,b=11分之一,求代数式a+2a+3a+...+9a+00a+10b+9b+...+3b+2b+b a-b>a,a+b 设a>b>1,且loga(b)+log(b)a=10/3,求loga(b)-log(b)a 因式分解:(a+b)²-10(a+b)+25.
