[shutup_aryan]

Thanks sir ❤️

Mein confuse ho gya tha

That A/B = root2 kese laau

It helped me a lot tq

[shreyanshmishra]

Sir a/b agar rational hai toh b obviously 0 se equal nahi hoga per a ho sakta hai toh hum kaise bol sakte hai ki b/a rational hoga

[HarashrajChundawat-kobj]

Thanku sir apne mujhe sikha diya rational number or irrational number kya hota hai mujhe to pata hi nahi tha 😂😂😂

[samarth_singh.one]

Sir, a/b is rational where b not = to 0
But how b/a is rational because a can be 0 because it's not mentioned that a not = to 0

[shishirgaur]

Sir, ek doubt hai aapne to sir a/b ko rational maana tha ar b not equal to 0 kaha tha par sir aapne a ko non-zero kaaaha kaha tha to phir sir b/a rational kaise ho gaya a to non zero nahi mention kiya gaya to a 0 bhi to ho sakta hai
