How do you prove 5/3 is irrational?

1 Answer

1. Let us assume that 5 – √3 is a rational.
2. We can find co prime a & b ( b≠ 0 )such that.
3. 5 – √3 = a/b.
4. Therefore 5 – a/b = √3.
5. So we get 5b -a/b = √3.
6. Since a & b are integers, we get 5b -a/b is rational, and.
7. so √3 is rational.
8. Let us assume that 5 – √3 is a rational We can find co prime a & b ( b≠ 0 )such that.

Is Root 5/3 an irrational number?

Root5 +3 is irrational number beacuse it is not perfect square………..

How do you prove an irrational number?

Let’s suppose √2 is a rational number. Then we can write it √2 = a/b where a, b are whole numbers, b not zero. We additionally assume that this a/b is simplified to lowest terms, since that can obviously be done with any fraction….A proof that the square root of 2 is irrational.

Is an irrational number then prove that 5 − √ 3 is an irrational number?

Since a & b are integers, we get 5b -a/b is rational, So we get 5b -a/b = √3 Since a & b are integers, we get 5b -a/b is rational, and so √3 is rational.

How do you prove that 5 is irrational?

Let 5 ​ be a rational number.

1. then it must be in form of qp​ where, q=0 ( p and q are co-prime)
2. p2 is divisible by 5.
3. So, p is divisible by 5.
4. So, q is divisible by 5.
5. Thus p and q have a common factor of 5.
6. We have assumed p and q are co-prime but here they a common factor of 5.
