Step-by-step explanation:
√7=a/b ( here a and b are co prime means they have only 1 as common factor. ... Here we find 7 is common which divide both a and b but this is contradiction because a and b are co prime they don't have common factor other than 1. So for our assumption is wrong. Hence √7 is irrational.
