K-map simplification

An SOP Boolean expression is defined as f=En(0, 2, 4, 5, 6). e the expression for f using x, y, z as inputs variable names (z=LSB) a. Writ b. Map the expression on a K-map Write the simplified expression in SOP form and draw the circuit : Transform the expression and draw the circuit using only 3 gates (one inverter, and two 2-input NAND gates) C. Now, use the concept of don't cares and update the K-map with the additional requirement 1 The inputs are such that y is never 1 when z Write the new simplified expression and draw the circut Redraw the circuit using only two 2-input NAND gates
