the Boolean function $)=(xz+x^{\text{'}}y+y^{\text{'}}z$ is implemented with NAND and inverter gates will be:

$F=((xZ{)}^{\text{'}}+(x^{\text{'}}Y{)}^{\text{'}}+(Y^{\text{'}}Z{)}^{\text{'}}{)}^{\text{'}}$

$F=((xZ{)}^{\text{'}}*(x^{\text{'}}Y{)}^{\text{'}}*(Y^{\text{'}}Z{)}^{\text{'}}{)}^{\text{'}}$

$F=((xZ)*(x^{\text{'}}Y)*(Y^{\text{'}}Z){)}^{\text{'}}$
