Question

)Prove that 9+3/7 is irrational.

Answer 1

Answer:

Step-by-step explanation:

Let us assume 9+3√7 is rational

Therefore 9+3√7=a/b

3√7=a/b-9

3√7=a-9b/b

√7=a-9b/3b

Therefore a-9b/3b is in the form of a/b which is rational number.

But this is contradicts the fact is that √7 is irrational number.

Therefore our assumption is wrong and 9+3√7 is an irrational number.
