Question

prove that root 3 + root 5 is an irrational​

Answer 1

Answer:

as p, q and 3 are integers p-3q/3 is a rational number. ... this contradiction has arisen because of our wrong assumption that 3+root 5 is a rational number. hence 3+ root 5 is an irrational number.

Answer 2

Answer:

let our assumption is 3+root 5 is a rational

3+root 5 =p/q (q not equal to 0)

root 5=p/q-3

root 5 =p-3q/q

therefore.........

iur assumption is wrong 3 plus. root is a irrational number
