Welcome to FRAC
Fungicides have become an integral part of efficient food production. The loss of a fungicide to agriculture through resistance is a problem that affects us all.
FRAC works to prolong the effectiveness of fungicides liable to encounter resistance problems and to limit crop losses should resistance appear.

(-1)^8÷(-2+1+1/2)^2-【2-(-2/3)^3×(-4/3)^2-3^2-(-2)^3】×(-1)^2011=1÷1/4-(2+8/27×16/9-9+8)×(-1)=4+2+128/243-9+8=5+128/243=

若a=(-1)++(-1)的2次方+(-1)的4次方+······+(-1)2011次方,且(ab+3)的2次方+b+c的绝对值=0,
求5c分之3b-2b,急急急急
;(5c)=(-3-6)/+|b+c|=0两项均是非负项,和为0那么两项都是0∴ab+3=0且b+c=0∴b=3.+(-1)+1+(-1)
【前2010项和为0!∴(3a-2b)&#47.a里面应该有(-1)^3吧-1的奇次方为-1..,最后一项为-1】
=-1∵(ab+3)&#178,-1的偶次方为1∴a=(-1)+(-1)的2次方+(-1)^3+(-1)的4次方+······+(-1)2011次方
= -1+1-1+1+..,c=-3应该是3a-2b吧.;(-15)=3&#47

疑a=(-1)+(-1)^2+(-1)^3+……+(-1)^-1+……+1-1=-1(3-b)^2+b+|c|=0
b^2-5b+9+|c|=0
(b-5&#47,右边为0;4,不能做;2)^2+11/2)^2+9-25/4+|c|=0左边的最小值是11&#47。题目有问题,这是不可能的;4+|c|=0
a=-1ab+3=0b+c=0可得b=3 c=-3可得结果为、、、为什么是3b-2b?
