Question

solve ch1...........​

Answer 1

Step-by-step explanation:

Let root p as rational no.

where root p=n/s and n, s have another common no. than 1 i-e., to form a/b. a/b are prime no..

root p = a/b

by cross multiplication,

b root p = a

squaring both sides,

pb=a

now,

pb=c square

p=c

hence

it is irrational no..

similarly,

root r = irrational no..

root p + root r

both are irrational no..
