(16a^2-1)/(4a-1)(16a^2-1)/(4a-1)(16a^2-1)/(4a-1)(16a^2-1)/(4a-1)=(4a+1)(4a-1)/(4a-1)=4a+1
(16a^2-1)/(4a-1)
(16a^2-1)/(4a-1)
(16a^2-1)/(4a-1)
(16a^2-1)/(4a-1)
=(4a+1)(4a-1)/(4a-1)
=4a+1
(1-16a×a×a×a)÷(4a×a+1)÷(2a+1)²
(1-16a×a×a×a)÷(4a×a+1)÷(2a+1)
a(a-1)(a-2)(a-3)(a-4)因式分解
【1】a+a=a×a a= [ ]【2】a×a=a÷a a=[ ]【3】a×a=a-a a=[ ] [4]a-a=a+a a=[ ]
计算[(a-1)/a*a-4*a+4]-[(a+2)/(a*a-2*a*a)]-4/a
a+a+1+a+2+a+3+a+4+a+5+a+6+a+7.+a+2013+a+2014=?
幂的计算题1、a×a^2×a^3×a^4×a^52、a+2a+3a+4a+a×a^2×a^3×a^4
(a+1/a)(a^2+1/a^2)(a^4+1/a^4)(a^8+1/a^8)(a^16+1/a^16)(a^32+1/a^32)(a^2-1)
a/a^2-4 a-1/a-2 a+2/a^2-4a+4
已知a^2+2a-1=0,求(a^2-16)/(a^3+4a^2+4a)乘以(a+2)/(a-4)除以(a+4)+3
[(a/a-2)-(a/a+2)]÷4a/2-a,其中a=-1/2
(a+1/a方-a+4/1-a方)/a方+2a-3/a+3
[a^2-4/(a-3)(a+2)+(a+2)/a-3]除以a+1/a-3
[a-a/(a+1)]÷(a²-2a)/(a²-4)×(a+1)/(a²+4a+4)
a=-1 求a-2a+3a-4a+5a-6a+...+99a-100a
(a+4)(2a+1)(a-3)
(4a+1)( )=16a^2+8a+1
