Decide whether the following statements are true or false. ltthe statement is false give a counterexample. otherwise leave the eld empty. (1) Let the binary,r operation 33 :E x Z } E be given by a 63 b {a + 21}. select v The identity element with respect to GB is 2. Counterexample: The statement is false, because for b :2E] E E we have 2 63 11 5E b. (2) Let the binaryr operation lg :34, X 34, } Ed be given lay-11$ b = (a. - b] mod 4. select v The identityr element with respect to g is 1. Counterexample: The statement is false, because for I: :=D E E4 we have 1 13: b #4. b. [3) Let the binaryoperationw:312 x Eu } Eu be given byoeb (ab) mod 12. select v The identityr element with respect to w is 1G. Counterexample: The statement is false, because for I: :=D E 312 we have 10 4r E} # b
