Question

prove that is7 - 2 root 3 is an irrational number​

Answer 1

Answer:

7+2under root 3 is an irrational number

Step-by-step explanation:

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

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-7p-7q÷2q =under root 3 . Hence under root 3 is an irrational number and p-7q÷2q is an rational number . Irrational number is not equal to Rational .Thus our supposition is wrong that 7+2under root 3 is a rational number . Hence 7+2under root 3 is an irrational number
