how can you write max term f(A,B,C,D)= minterm f(A,B,C,D)

the right way is minterm = (maxterm)'

therefore

f(A,B,C,D)=∏M(0,1,3,4,5,7,9,11,12,13,14,15) = [ f(A,B,C,D) = m(0,2,6,8,10) ]'

the right way is minterm = (maxterm)'

therefore

f(A,B,C,D)=∏M(0,1,3,4,5,7,9,11,12,13,14,15) = [ f(A,B,C,D) = m(0,2,6,8,10) ]'
