(10^2)^3(-a^3)^5(a^2)^3(a^2)^5(a-b)^n[(b-a)^n]^2
(10^2)^3(-a^3)^5(a^2)^3(a^2)^5(a-b)^n[(b-a)^n]^2
a^(n+1)b^n-4a^(n+2)+3ab^n-12a^2
(a-b)(a^(n-1)-b^(n-1))=(a-b)^2(a^(n-2)+a^(n-3)b+……+ab^(n-3)+
已知a^3n=5,b^2n=3 ,求a^6n b^4n
已知n是正整数,a-2b=-1,求3(a-2b)2n+2(2b-a)2n-1+5(a-2b)2n-1-2(a-2b)2n
-2n-(3n-1) a-(5a-3b)+(2b-a) -3(2s-5)+6s 1-(2a-1)-(3a+3) 3(-a
(3a的n+2次方b-2a的n次方b的n-1次方+3b的n次方)*5a的n次方b的n+3次方(n为正整数,n大于1)
a(n+1)=2an-a(n-1) 3bn-b(n-1)=n
已知,9a^n-3b^2n与-2a^3mb^5-n的积与5a^4b^9是同类项,求m,n
已知(a^m+1 b^n+2)(a^2n-1 b^2m)=a^5 b^3,求m-3n的值
(a^m+1b^n+2)(a^2n-1b^2m)=a^5b^3,求m-3n的值
向量的运算:若m(3a-2b)+n(4a+b)=2a+5b,求n,n的值
