Question

prove that 7-2root3 is a irrational ​

Answer 1

Answer:

Show that 7+2 under root3 is irrational no

let 7+2under root 3 be an rational number . Then it must satisfy the condition of rational number that is 7+2 under root 3=p/q or 2 under root 3 = p/q-7.

p-7q÷2q =under root 3 . Hence under root 3 is an irrational number and p-7q÷2q is an rational number .

Answer 2

Answer:

let 7+2under root 3 be an rational number . Then it must satisfy the condition of rational number that is 7+2 under root 3=p/q or 2 under root 3 = p/q-7. p-7q÷2q =under root 3 . Hence under root 3 is an irrational number and p-7q÷2q is an rational number .
