Question

prove that 3√2 anirrational?​

Answer 1

Answer:

3+√2 = a/b ,where a and b are integers and b is not equal to zero .. therefore, √2 = (3b - a)/b is rational as a, b and 3 are integers.. But this contradicts the fact that √2 is irrational.. So, it concludes that 3+√2 is irrational..

Answer 2

Answer:

Let us assume, to the contrary, that 32 is.

⇒ 2 is rational ...[ ∵3,a and b are integers∴3bais a rational number]

This contradicts the fact that 2 is irrational.

Hence, 32 is an irrational number.
