enter image description here

$Y = \underline{A} B +A \underline{B}+A \underline{CD}$

Let, $P = \underline{A} B, Q = A \underline{B}, R =A \underline{CD}$

Therefore, Y = P+Q+R

$\underline{\underline{Y}} = \underline{\underline{P+Q+R}} ….\text{taking double inversion}$

$Y = \underline{P}.\underline{Q}.\underline{R} ....\text{De Morgan’s Theorem}$

Therefore, $Y=\underline{\underline{AB}.\underline{A \ B}.\underline{A\underline{CD}}}$
