@皮农2003:在逻辑表达式中,非A+AB等于多少 -
毛狐19347635032…… 逻辑函数中,有A=A+AB的公式 所以A+非AB =A+AB+非AB (依据A=A+AB) =A+(A+非A)B (依据AB+非AB=(A+非A)B) =A+B (依据A+非A=1) 就这样证明出来了啊.

@皮农2003:高中不等式中,有一常用不等式是ab≤[(a+b)/2]²或ab≤(a²+b²)/2. -
毛狐19347635032…… 两个不等式都对,在不同的情况下使用,只不过确定的ab的范围不同,比如说ab=3,可能[(a+b)/2]²的值为4,(a²+b²)/2的值为5,都是成立的 PS: ab≤[(a+b)/2]²和ab≤(a²+b²)/2都是由(a-b)²≥0推导出来的,但[(a+b)/2]²≤(a²+b²)/2

@皮农2003:give+a+thought+to是什么意思 -
毛狐19347635032…… give a thought to 译为....给想...1.In those cases, you translate the verb or noun and don't give a thought to the preposition in the source language: just use the preposition required in the target language. 在这种情况下,你翻译动词或者名词,不要考...

@皮农2003:逻辑代数的分配律A+BC=(A+B)(A+C)怎么证明? -
毛狐19347635032…… (A+B)(A+C) =AA+AB+AC+BC =AA+A(B+C)+BC =A+A(B+C)+BC =A(1+B+C)+BC =A+BC

@皮农2003:逻辑电路题化简成最简与或式y=((AB)'+A'+B'+AB)'('代表非的意思)求具体化简过程 - 作业帮
毛狐19347635032…… [答案] A'+B'=(AB)' y=((AB)'+(AB)'+AB)'=((AB)'+AB)'=(1)'=0

@皮农2003:a+b分之2加a+b分之2=ab分之1 求a分之b+b分之a=? - 作业帮
毛狐19347635032…… [答案] 2/(a+b)+2/(a+b)=1/ab (且a+b不等于0) 4ab=a+b … b/a+a/b =[(a+b)^2-2ab)]/ab =(16ab-2ab)/ab =14ab/ab =14

@皮农2003:1/a+1/b= 4/a+b,则分式b/a+a/b - 作业帮
毛狐19347635032…… [答案] 两边同时乘以ab(a+b) b(a+b)+a(a+b)=4ab 化简:a^2-2ab+b^2=0 (a-b)^2=0 a=b b/a+a/b=2

@皮农2003:逻辑函数A+非AB怎么等于A+B - 作业帮
毛狐19347635032…… [答案] A+ ┐AB =A(1+B)+┐AB =A+AB+┐AB =A+(A+┐A)B =A+B 满意请轻戳此处 ↓
