Hii hlo. pls tell me prove that 5-3/7√3is irrational​

Answer»

ANSWER:

Proving:

let 5-2/7√3 be rational no.

therefore

5-2/7√3=p/q

(where p and q are co PRIME)

2/7√3=5-p/q

2/7√3=5q-p/q

√3=7(5q-p)/2q

here 7,5,2,q,and p are integers.

therefore 7(5q-p)/2q is rational

therefore √3 is rational no

but this contradicts the FACT that √3 is irrational no

therefore 5-2/7√3 is irrational no.

hence proved.
