Question

(1) Show that 4 v2 is an irrational number.​

Answer 1

The answer is:

Explanation:

Let us assume that 4√2 is a rational number.

Which means that 4√2 = a/b

( bcoz a rational number is a number in the a upon b form where b is not zero)

4√2 = a/b

√2 = a/4b

But√2 is an irrational number

and a/4b is a rational number

•Our assumption, that is 4√2 is a rational number was wrong.

•So 4√2 is an irrational number
