Q.1 Prove that under root 37 is an irrational number
Answers
Answer:Then it can be written in p/q form where q is not equal to zero. ... But p and q are co-prime. Hence,This contradicts our assumption. Therefore , √37 is irrational.
Step-by-step explanation: Let us assume√37 be rational number.
Then it can be written in p/q form where q is not equal to zero.
√37=p/q
√37 p=q
( Squaring both sides)
37p^2=q^2. { 1}
As 37p^2 is divisible by q^2
Therefore 37p is also divisible by q.
Let q be 37c where c is rational number.
q=37c
(Squaring both sides)
q^2 = 1369 c^2
As q^2 =37p^2 ( from 1)
37p^2=1369c^2
37c^2=p^2. (2)
37 is a factor of p^2
Therefore 37 is also a factor of p.
From 1 and 2 :
37 is common factor of p and q.
But p and q are co-prime.
Hence,This contradicts our assumption.
Therefore , √37 is irrational.
Hence Proved........
Thank u
Answer: If √37 is rational it should be written in the form of p/q where q is not equal to zero.
Here √37 cannot be written in the form p/q.
Hence it is irrational
