please i need the solution of all questions urgently

1. Convert the following numbers to the given bases i) (LEOCOBI.2FF074), to an octal number ii) (274.024), to base 5 ii) (120232), to a decimal number iv) (IBA)s to base 7 2. Find the r's and (r-1)'s complement of the following numbers i) (7430), ii) (1350078300), iii) (110010110 iv) (AB16F.C50), 3. Perform the subtraction with the following numbers using r's complement approach in baser a) (17.2), - (45.25), b) (1101.10), -(11011), 4. Find the dual and also the complement of the functions given below i) F(x,y,z)=x'y+(y+z'/(xy+z') ii) F(A,B,C,D,E)=CDBA'+(BCD+BWAE+C)(AC+DE) 5. Given the Boolean Function F(x,y,z,w)= wz+(yex) 1) Draw the logic diagram of the function F using only 2-input NOR gates. ii) Draw it once more using only 2-input NAND gates. 6. Express the following functions in their canonical form (i.e. as a sum of minterms and also the product of maxterms) a) F(x,y,z,w)=(xy+wz')(w'+2)+x'yzw+xyzw b) F(A,B,C,D)=(A'D'+B+AC)(BC+CD+ABD')+ A'BCD
