Question

In the group (G={0,1,2,3,4},+5) the inverse of $open parentheses 2 plus 5 to the power of 2 minus 1 end exponent close parentheses$ is

0
1
2
3

The correct answer is: 1

Since $2 plus subscript 5 end subscript 2 to the power of negative 1 end exponent equals$ Identity element = 1.
Therefore, $left parenthesis 2 plus subscript 5 end subscript 2 to the power of negative 1 end exponent right parenthesis to the power of negative 1 end exponent equals 1.$
