Find minterm or maxterm depending on the symbol given for each of the following cases:

a$)$ Given $4$ input variables: A$,$ B$,$ C$,$ D

What would be expression for M$11$

$($hints: Write $11$ into binary using $4$ bits, that will give you the values of A$,$ B$,$ C and

D$)$

b$)$ Given $3$ inputs variables: x$,$ y$,$ z$,$ find the expression for m$4$

c$)$ Given $5$ input variables: a$,$ b$,$ c$,$ d$,$ e$,$ determine m$21$

d$)$ Given $5$ input variables, a$,$ b$,$ c$,$ d$,$ e$,$ determine M$7$

e$)$ Given $4$ input variables X$,$ Y$,$ Z$,$ U$,$ determine m$5$
