Can you please explain step by step on how to do each of these two problems below? And then tell me whether it involves an arithmetic sequence or a geometric sequence I also need to show the work on both problems thank you.
Perform the indicated operations
1010 two × 101 two
A25 sixteen × 4 sixteen
IN this, it is easy by shifting registers, one of the great advantages of binary.
1010 x 101= 1010+101000 and add
110010 (check the add, I did it in my head.)
4x5 = 20= 16+4 or 14
4xA=40=2x16+8 or 28
++80plus signs are inserted to line up
total 2894 check that.
