plz mark as brainliest

Step-by-step explanation:

∴ It can be expressed in the form p/q where p,q are co-prime integers. ... Therefore, p/q is not a rational number. This proves that √5 is an irrational number

Answer 2

Answer:

yes root 5 is irrational

Step-by-step explanation:

let us assume root 5 is rational

root 5 = a/b = a = b root 5

squaring on both sides

5b^2=a^2

by statment 1 it follows if 5 divides a^2 it also divides a

we can write a=5c for some integer

by substituting a  we get 5b^2=25c^2

b^2=5c^2

b^2=5c^2 is rational but  according to contradicts root 5 is irrational
