Question

prove that 3+ root 5 is an irrational number​

Answer 1

Answer:

Well it's already irrational !

Step-by-step explanation:

Let assume it as rational and Take x as equals to the whole equation.

Whereas X is rational number

X = 3 + root 5

Move 3 to other hand with changing it's positivity to negativity.

X-3 = root 5

We know that, root 5 is irrational and 3 is rational and also we assumed x as rational.

So The Equation 3+ root 5 is also irrational.
