    hi, guys....i need some help with these question...i will be grateful if u could help me...

    simplification using boolean algebra only..

    A) F1 = w'x' + (w'x')'

    b) F2 = w(w + w'xy)

    c) F3 = xy(v.v')

    d) F4 = (v + (wy)')'

    e) F(v,w,x,y) = F1+F2+F3+F4


    thank you in advance

    if ' means bar then solution might be

    f1=w'x'+(w'x')'
    for this now let w'x' be a then
    f1=a+a' that is f1=1;
    let me explain this
    suppose a=1 then a'=0 in this case f1=1;
    and if a=0 then a'=1 in this case also f1=1;
    hence f1=1 always...

    now going for f2=w(w+w'xy)
    or f2=ww+ww'xy and as ww=w and ww'=0 always
    therefore f2=w....

    now f3=x.y(v.v') then v.v'=0....
    therefore f3=0....

    now F4 = (v + (wy)')'
    using de'morgans law
    f4=(v+w'+y')'..
    and again we will use de'morgans law..
    f4=v'wy..

    therefore..

    F(v,w,x,y) = F1+F2+F3+F4=1+ w+0+v'wy..

    i think i have tried my level best...
