A) \[{{c}^{-1}}{{b}^{-1}}{{a}^{-1}}\]
B) \[{{b}^{-1}}{{c}^{-1}}{{d}^{-1}}\]
C) \[{{a}^{-1}}{{b}^{-1}}{{c}^{-1}}\]
D) \[{{b}^{-1}}{{c}^{-1}}{{a}^{-1}}\]
Correct Answer: A
Solution :
A group G with elements a, b, c, d or\[a,b,c,d,\in ,G\] property of group that \[{{(ab)}^{-1}}={{b}^{-1}}{{a}^{-1}}\] Therefore \[{{(abc)}^{-1}}={{c}^{-1}}{{b}^{-1}}{{a}^{-1}}\]You need to login to perform this action.
