Question

prove root 7 Is irrational by long division method​

Answer 1

Answer:

Here 7 divides b² so for 7 divides b. 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
