Assuming, there is no overflow, do the following:

a$)$ Write an expression that uses only shifts and adds to multiply unsigned integer x by $50.$

b$)$ Using shifting, adding and subtracting, write an expression to multiply unsigned integer x by $1237$ with minimum number of operations. $($You will get partial points if you use more operations than the mimum$)$

c$)$ Write an expression using shifts and addition to perform the following operation on an unsigned integer x;

$(5/4)*$x
