Answer 2

Answer:

Question = 7√ 2 is irrational

ANSWER - Let us assume to the contracy that 7√2 is rational . There exists 2 integers a and b [b≠0] such that ,

7√2 = a\b   Where a and b are co primes .

hence , √2 = a\ 7b

now a , b and 7 are integers .

a\7b is rational .

so √2 is rational , This is a contraduction to our assumption that 7√2 is rational .

SO , 7√2 IS IRRATIONAL .
