Answer 1

Answer

Hint: Here we will first take an assumption that 5+√2 is an rational number and then write it in the form of ab and then solve both the sides to get the desired answer. Therefore the quantity a−5bb is rational. ... Therefore, 5+√2 is an irrational number. Hence proved.

Answer 2

Answer:

5 -2under root 3 = a/b

2√3=. -a/b+5/1

√3=. -a/b+5/1

2

it is showing that √3 we know it is irritional but they show irritional equals to rational hence contradiction our assumption it is irritional
