yarr how to solve these all sum... unable to do

Answer 1

Hello dude this is the solution book of RD

Sharma!!

Well, first of all thanks for asking the question, I will be trying my best to give you the best solution possible!!!

Just keep in mind that, irrational numbers cannot be classified in p/q form!!

1) 3/81= 1/27 and it’s root will be 3 root 3

And since foot 3 is irrational so this whole term will be irrational.

2)no perfect root 0f 361 so irrational.

And thus this will be carried out for long 1.23232323232...as it going like this it is relating and recurring so it is rational...

Hope this will be helping you!!

Thanks!!
