Realize the following functions using NAND gates only

$F=(AB{)}^{\text{'}}+A+(B+C{)}^{\text{'}}$

$F=A+BC{D}^{\text{'}}$ Draw the following functions using NAND gates only: F$($A$,$B$,$C$,$D$)=($A$$B$$CD$+$ A$$D $+($B$+$D$))$ please draw a gate do not just write a gate name please draw a actual gate and show all the work that needed for this question
