if e is an identity element in Z then a*e=a a.e/2=a e=2 option A

why not option d?

no a*1/2=a/4≠a so not option D

samaj nahi aaya pls explain it again?

a*e=a it you take e=1/2 then a*1/2=(a.1/2)/2=a/4≠a

mere wale tarike se "e" galat que aa raha hai?

Identity se inverse calculate karnete hai na ki inverse se inditity this ur mistake

par isme galat kya hai elemnt*elemntinverse = identity. isme kya galat hai sir?

???

pahle identity calculate Karte hai fir inverse . aap ko ye pata kase laga ki a ka inverse a^-1 hai wo to multiple ke liye hota hai

for identity always use a*e=a

a^-1 toh maan ke chalte hai in general kewal multiplication ke liye he nahi ainverse toh kisi bhi operation ke liye hum maan ke chalte hai na sir.

but ye necessary nahi ki har operation ke liye b=a-1
