is it boolean?

I see it as boolean, not derivative, If it 's so, let me know. I don't want go tooo far on the wrong way, (may get ticket from 911 :( , :) )

I'll be there now. but since we are here to help him/her. Would you please give out the answer before leaving? don't let him/her wait while we can, ok?

yes we can simplify this

We can use Demorgan's Theorem: ( x + y ) ' = x'y' (xy)' = x' + y'
 one year ago

perl Group TitleBest ResponseYou've already chosen the best response.1
(x'z'+xy')' = (x'z')' (xy')' = (x'' + z'' ) (x' + y'' ) = (x + z ) (x' + y )

one more step, friend, you have form of xx'
 one year ago

perl Group TitleBest ResponseYou've already chosen the best response.1
(x'z'+xy')' = (x'z')' (xy')' = (x'' + z'' ) (x' + y'' ) = (x + z ) (x' + y ) = xx' +zx' +xy +zy = zx' + xy + zy

but it seems the answer is: z(x'+y)!

@ketz I am with perl. I don't get yours

I think the answer needs to be converted to MMF
 one year ago

Hoa Group TitleBest ResponseYou've already chosen the best response.0
no need to get that form if the form is reducible . perl's answer is irreducible form that 's all you need

perl Group TitleBest ResponseYou've already chosen the best response.1
you claim that (x'z'+xy')' = z ( x' +y ) ?
 one year ago

perl Group TitleBest ResponseYou've already chosen the best response.1
i think thats false, plug in values for x,y,z
 one year ago

ketz Group TitleBest ResponseYou've already chosen the best response.0
but How to convert it to Minimal Multiplicative Form (MMF)? any idea guys?
 one year ago

perl Group TitleBest ResponseYou've already chosen the best response.1
can you double check you copied problem correctly

@ketz don't combine many problems into 1. that's another process, post a new one
 one year ago

perl Group TitleBest ResponseYou've already chosen the best response.1
Plug x=1, y=1, z = 0 into (x'z'+xy')' (1' & 0' + 1&1')' = ( 0 &1 + 1 & 0 )' = ( 0 +0 )' = 0' = 1 Now plug x=1 , y = 1 , z = 0 into z ( x' +y ) 0 ( x' +y) = 0 , because 0*x = 0 clearly they are not equal

ketz theres a typo somewhere
 one year ago

Hoa Group TitleBest ResponseYou've already chosen the best response.0
@perl ketz asks about the way how to get the MMF form. not the original problem. All we need is a new problem such that we get the MMF form or we can manipulate the answer to get that form. However, by that step, we make the answer more complicated than it is. We can separate it into new topic as: convert zx' + xy + zy into MMF form
 one year ago

perl Group TitleBest ResponseYou've already chosen the best response.1
MMF is product of sums so (x'z'+xy')' = (x'z')' (xy')' = (x'' + z'' ) (x' + y'' ) = (x + z ) (x' + y )

i dont know why hes not accepting it?

perl Group TitleBest ResponseYou've already chosen the best response.1
(x'z'+xy')' =/= z(x'+y)
 one year ago

perl Group TitleBest ResponseYou've already chosen the best response.1
=/= means not equal
 one year ago

Hoa Group TitleBest ResponseYou've already chosen the best response.0
because there is another way to get that form .
 one year ago

perl Group TitleBest ResponseYou've already chosen the best response.1
they are not equal, i proved it
 one year ago

perl Group TitleBest ResponseYou've already chosen the best response.1
Plug x=1, y=1, z = 0 into (x'z'+xy')' (1' & 0' + 1&1')' = ( 0 &1 + 1 & 0 )' = ( 0 +0 )' = 0' = 1 Plug x=1 , y = 1 , z = 0 into z ( x' +y ) 0 ( x' +y) = 0 , because 0*x = 0 Therefore they are not equal

by multiply (x + x') into the term which doesn't have x, (y + y') into the term which doesn't have y and so on

I'm with you, you are 100% right. just misunderstand together with him

ok, let's go to his new one

perl Group TitleBest ResponseYou've already chosen the best response.1
so theres two forms, a product of sums, or a sum of products
 one year ago

perl Group TitleBest ResponseYou've already chosen the best response.1
(x'z'+xy')' = (x'z')' (xy')' = (x'' + z'' ) (x' + y'' ) = (x + z ) (x' + y ) < Product of Sums = xx' +zx' +xy +zy = zx' + xy + zy somehow we can get xy + x'z < sum of products (with no terms repeating_

This is a Boolean Calculator http://calculator.tutorvista.com/math/582/booleanalgebracalculator.html and i plugged in ~(~x & ~z or x & ~y)
