Question

-Prove that 5+3V5 is a irrational.​

Answer 1

• Rational Numbers are expressed in the form of p/q where p and q are integers and q is not equal to zero.

Here, 5 + 3V5 can be written as

5/1 + 3V5.

5/1 Is rational where 3V5 is irrational.

3V5 cannot be written as 3V5/1 as it contains a variable 'v'.
