IDK Proper explaination but u can just apply the formula....

Answer 2

Step-by-step explanation:

proof

if the possible ,let root 5 is a rational no. therefore it can be express in the form of p by q

therefore,√5 =p/q

p=(√5q)^2

p^2=5q^2( equations 1)

therefore 5divides p^2

5dividesp

there for p=5c (let)

from 1

(5c)^2=(5q)^2

25c^2=5q^2

5c^2=q^2

5divides q sq

5divides q

therefore q is also factors of 5

p and q have common factor as 5

so,this is contradiction to the fact that p and q are Co prime

so, our supposition are wrong

hence,root 5 is irrational
