Question

Show that 5+3under root 2 is an irrational number?

Answer 1

Answer:

Let us assume the contrary. That contradicts the fact that √2 is irrational. The contradiction is because of the incorrect assumption that (5 + 3√2) is rational. So, 5 + 3√2 is irrational.

Answer 2

Answer:

let 5+3under root 2 is an rational no. where a and B are co prime no. where b is not equal to 0.Then,

Step-by-step explanation:

5+3 under root 2= a/b

under root 2 =a-5b/3b

it is a fact that under root 2 is an irrational no.So,

5+3under root 2 is an irrational no.
