(a-b)(a+b)(aˇ2+bˇ2)(aˇ4+bˇ4)
(a-b)(a+b)(aˇ2+bˇ2)(aˇ4+bˇ4)
(a-b)(a+b)(aˇ2+bˇ2)(aˇ4+bˇ4)
(a-b)(a+b)(a^2+b^2)(a^4+b^4)
=(a^2-b^2)(a^2+b^2)(a^4+b^4)
=(a^4-b^4) *(a^4+b^4)
=a^8-b^8
原式=(a^2-b^2)(aˇ2+bˇ2)(aˇ4+bˇ4)=(aˇ4-bˇ4))(aˇ4+bˇ4)=a^8-b^8
(a-b)(a+b)(aˇ2+bˇ2)(aˇ4+bˇ4)
=(aˇ2-bˇ2)(aˇ2+bˇ2)(aˇ4+bˇ4)
=(aˇ4-bˇ4)(aˇ4+bˇ4)
=aˇ8-bˇ8
-2a(a+b)+b(a+b)
(a-b)(a+b)(aˇ2+bˇ2)(aˇ4+bˇ4)
(a+2b)(a-2b)+(a-b)(a+b)-2(a-3b)(a-b)
5(a*a*b-3*a*a*b)-2*(a*a*b-7*a*b*b)
-a-b+2b^2/a+b
化简:|a+b|+|b-a|+|2b|
|a+b|-|b-a|+|2b|化简哦!
a-b+2b²/a+b
通分a-b,2b^/a+b
化简(2a-b/a+b-b/a-b)除以a-2b/a+b
计算:((a+b)(a-b)-(a-b)^2+2b(a-b))/4(a-b)
化简(2a-b/a+b-b/a-b)除以a-2b/a +b
化简:{[(2a-b)/(a+b)]-[b/(a-b)]}÷[(a-2b)/(a+b)]
计算·[(2a+-b)/(a+b)-b/(a+b)]/(a-2b)/(a+b)
(a-b)(a+b)²-(a+b)(a-b)²+2b(a²+b²)
(a-b)(a+b)²-(a+b)(a-b)²+2b(a²+b²)
(2a-3b)[(a+b)-b(a-3b)]
化简:a-[b-2a-(a-b)]
