How do you prove 5/3 is irrational?
1 Answer
- 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.
- 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?

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.
| 2 | = | (2k)2/b2 |
|---|---|---|
| b2 | = | 2k2 |
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.
- then it must be in form of qp where, q=0 ( p and q are co-prime)
- p2 is divisible by 5.
- So, p is divisible by 5.
- So, q is divisible by 5.
- Thus p and q have a common factor of 5.
- We have assumed p and q are co-prime but here they a common factor of 5.
