Question

prove that5-√3 is a irrational no.

Answer 1

Answer:

Step-by-step explanation:

We know that ✓3 is irrational no.

So

Let us assume 5-✓3 is rational no.

Then5-✓3=p/q

-✓3=P/q-5

Iraational no. = Rational no.

Which can't be possible so it's irrational no.

Answer 2

If it's given that root 3 is an irrational number, then it's fine, if the question is of 4 marks and root 3 isn't given to be a rational number, you gotta prove root 3 irrational first.

Hope it helped you :)
