When the expression was :70 +20 root 10 all on 30 and how did you cancel the 2 0s at the numerator when the denominator is 30 with only one 0 ?

[vuttklb]

When finding a conjugate, and the sign is negative you change it positive and when is positive you change it to negative 👍👍👍

Why do you know it's addition when writing the second formula?

[Blinkarmy]

Nice explanation thanks for your suggestion😊

[Treasoner]

Whoever is saying this is wrong then answer the right answer then.

[AnthoniaAyingangba]

Pls hw did u get de final answer to be positive 3

[SyedAbidHussain-qy]

Can you explain how did you factor out the zeros in the last step ?

[Kavitha-nmwz]

Sir can you explain the rationalizing factor in questions related to byju's 9th IIT

[LindelwaMabuza-eosy]

Is there any simpler way to simplify this

[TonoLord]

I don't know what and where? But i feel like you made error

[malkimchannel]

I think you have gotten the conjugate wrong sir.. I think on both denominator and numerator it’s suppose to be +.
