if root 3 is irrational, prove that 5-3 root 3 is irrational.
pls answer
Answers
Answer: I hope this helps. The answer is down below
Step-by-step explanation:
Let us assume that 5 - √3 is a rational We can find co prime a & b ( b≠ 0 )such that 5 - √3 = a/b. Therefore 5 - a/b = √3. So we get 5b -a/b = √3 Since a & b are integers, we get 5b -a/b is rational, and so √3 is rational. But √3 is an irrational number. Let us assume that 5 - √3 is a rational. We can find co prime a & b ( b≠ 0 )such that ∴ 5 - √3 = √3 = a/b. Therefore 5 - a/b = √3. So we get 5b -a/b = √3. Since a & b are integers, we get 5b -a/b is rational, and so √3 is rational. But √3 is an irrational number Which contradicts our statement ∴ 5 - √3 is irrational
