alleryପୂର୍ଣ୍ଣସଂଖ୍ୟା n କ’ଣ ଧନାତ୍ମକ? I: n ର ବର୍ଗ n ସହିତ ସମାନ। II: n ଶୂନ ନୁହେଁ।
Aକେବଳ I ଯଥେଷ୍ଟ
Bଉଭୟ ଏକତ୍ର ଆବଶ୍ୟକ
Cକେବଳ II ଯଥେଷ୍ଟ
Dଏକତ୍ର ହେଲେ ମଧ୍ୟ କୌଣସିଟି ପର୍ଯ୍ୟାପ୍ତ ନୁହେଁ
Answer & Solution
Correct answer: B. ଉଭୟ ଏକତ୍ର ଆବଶ୍ୟକ
n ର ବର୍ଗ n ସହିତ ସମାନ ହେବା ଦ୍ୱାରା n = 0 କିମ୍ବା 1 ମିଳେ, ଏବଂ 0 କୁ ବାଦ୍ ଦେଲେ n = 1 ରହେ, ଯାହାକି ଧନାତ୍ମକ ଅଟେ।
