化简并计算,（a-3b)(a-3b)+(3a+b)(3a-b)+(a-5b)(a+5b),a=-8,b=－6

化简并计算,（a-3b)(a-3b)+(3a+b)(3a-b)+(a-5b)(a+5b),a=-8,b=－6 计算(a-b)^m(a-b)[2(b-a)]^3[(b-a)^5]^2÷(a-b)^m= (3a-6b)/(a+b) - (5a-6b)/(a-b) - (4a-5b)/(a+b) - (7a-8b)/(a-b (3a-6b/a+b）-(5a-6b/a-b)-(4a-5b/a+b)-(7a-8b/b-a) 若a,b满足|a+5b-2|+(a+b-6)²=0,求代数式（a-3b)(a+2b)-(a+5b)(a+3b) 化简求值a/(a-b)+b/(a+b)+b^2/(a^2-b^2) 当a:b=3: 已知：a、b满足b=√a-2+√（6-3a）+5,化简并计算：√a·√a/b÷√2b/a×√2b/a 若a-b=5,ab=-6,求（a+b)(a+b)-3(a+b)(a-b) 计算：3a+4b/a-b+3b/b-a-4a/a-b 计算代数式a-b+(a-2b)(a-b)+(a-2b)(a-b)²+(a-2b)(a-b)^3 当a=-3&# 计算:(b-a)^5(a-b)^m+(a-b)^(m+3)(b-a)^2 计算:(a-b)^m+3(b-a)^2(a-b)^m(b-a)^5
