Question

Prove that 7 root 5 is not a rational number

Answer 1

Answer:

HOPE THIS BRING A SMILE IN YOUR FACE

Step-by-step explanation:

Let us assume 7√5 is rational

7√5 =a/b, a nd b are co-primes, b is not 0

√5=a/7b

Since a and b are co-primes,

a/7b is rational and hence √5 is rational.

But we have proved that √5 is rational.

Thus contradiction has arisen because if our incorrect assumption.

Therefore, 7√5 us irrational.

Answer 2

If we solve we get 5 (power)1/7

and rational number not have factional power

this proves that 7root 5 is not an rational number it is an irrational number.
