Question

2. Prove that 3 + 2/5 is irrational.​

Answer 1

Hey mate here is your answer...

Suppose, 3+2√5 is irrational.

Take two integers a and b, such that 3+2√5 = a/b and suppose a and b are co-prime.

2√5 = a/b - 3

√5 = a / 2b - 3/2

Now, a/2b - 3/2 is irrational.

So, √5 is also became rational.

But we know that √5 is irrational.

Therefore, our assumption is wrong.

So, 3+2√5 is irrational.

Hope it help you.... So, plzzzzz mate Mark my ans as brainliest answer....
