4. What would be then minimum number of binary variables required to represent a variable that can take on an integer value in the range of 15 to 25 ? 5. Draw the truth table for \( \mathrm{F}(\mathrm{A}, \mathrm{B}, \mathrm{C})=\mathrm{A}\left(\mathrm{b}^{\prime}+\mathrm{c}^{\prime}\right) \) 6. Simply the following Boolean expressions as much as possible (give justification for each step) \[ A B+B C(B+C) \] 7. Create the truth table for \( \mathrm{F}(\mathrm{X}, \mathrm{Y}, \mathrm{Z})=\mathrm{X}+\mathrm{Xx} ' \mathrm{Y}+\mathrm{Yz} \) ( or \( \mathrm{X}+\mathrm{XY}+\mathrm{Yz}) \)
