Galois Field 2 Listen to the youtube video on my channel called Galois Field 2 and then answer the following questions. The YouTube link can be found here: https://youtube/rfCSctixQKw. (you may need to copy and paste this into your browswer) 7. Calculate each of the following expressions over GF(2): a) 1+1+1+0 = b) 1 . 1 +0 . 1 +0 . 0+1 . 1= c)(1 + 1 +1) . (1+1+1+1) = d) 1-1-1-1-1-1-1-0= e) (1 - 1) - (0 - 1) = 8. List all 8 vectors in GF(2)3 9. Show that the set of all possible linear combinations of I and over the field GF(2 ) is GF(2)2. That is, show Span( " , ;)-GF(2)2
