直播哦小弟先行谢过高手出现吧 麻烦写过程~囊中羞涩我已经把仅有的都给你了~
数学题目求解决拢共十三道题目~(1). 10000x10^m(2) (-5)^10x(-5)^2 x5^3(3)(x-2)^2n-1 x (2-x)^2n+1+ (x-2)^4n (4) a^x=2, a^y=3 求a^2x+3y(5) y^2 X y^m-2+y X y^m-1-y^3 X y^m-3 (6) m^3Xm^6+(-m^3)^3 (7)
(1) 10^(m+4)指数相加
(2) 5^15,指数相加
(3)(x-2)^(2n-1) x (x-2)^-(2n+1)+ (x-2)^4n=(x-2)^(4n-2)
(4) a^2x=4,a^3y=27 a^2x+3y=31
(5) y^(2+m-2)+ y^(m-1)-y^(3+m-3)=y^m + y^m - y^m=y^m
(6) m^(3+6)+(-1)^3(m^3)^3=0
(7) (x^2)^2 X x^2-(-x^2)^3=x^(4+2)-(-1)^3x^3x2=2x^6
(8) 3^2x^2y^2x2+(-xy^3)(4xy)=9x^2y^4-4x^2y^4=5x^2y^4
(9) x^3a=(x^a)^3=8,y^2b=(y^b)^2=9 x^3a X y^2b=72
(10) -6a^2bc/-12ab^2=ac/2b
(12) 先去括号:x^2y^2/(x-y)^4 X y^3(y-x)^3/x^3=y^5/x(y-x)
(13) a-b/a^2+ab X a^2b^2-a^4/ab-a^2
