E book kab Tak aayega

[@mohdarif3912]

When putting a and b is equal to any real number. Then a plus b by 2 is always be a real number. So, it operation is binary operation.

[@swetaroychowdhury6576]

Its really helpful for me .....thx a lot for ur explanation sir

[@saurav_pathak_]

Sir last wala question mee closure law hold hoga aur ye question binary operation hoga 💓💓💓💓Thank you sir💓💓💓💓

[@sharmag2564]

Yes, last one is a binary opretion

[@syedtanzeelshaz1426]

In the 2nd question: if we take a=1 and b=0 (as input) and here a,b belongs to R then, a*b= a/b = 1/O ,which does NOT belongs to R Thus, the output does NOT belongs to R. Therefore , this operation is not binary.

[@Nitin_sharma_026]

Whenever it given b=0 Then the operation is not binary But there is no given value of b Then let put any value N And prove the operation binary operation.

[@surendrakverma555]

Good

[@EAT1951]

Sir what is the difference between binary operation and closure law... is there any example for binary opearation but not closed

[@NishantKumar-ji1lf]

binary operation is based on closure law

[@islamicbrotherhood9574]

Sir what if b=0 in part ii?

[@Nitin_sharma_026]

If b=0 then it's not binary operation But if b=0 given There is any given for b So Let any N for value of b Whenever b=0 given then it's not binary operation. But there is no any given... So it's a binary operation.

Sir Kya 0°=360° ho sakta hai??

[@brijhmohansharma7435]

No. Because 0 degree means nothing and 360 degree means a circle.
