Question

Prove 5 - √2 is irrational , given that √2 is irrational.

Answer 1

Answer:

3+(80)x+y is the answer

Answer 2

Step-by-step explanation:

Let us assume

(5 - √2) is a rational number

We know that ,

Rational number is in the form of $\frac{p}{q}$ where q ≠ 0 .

→ $\frac{p}{q}$ = ${(5~-~√2)}$

→ √2 = 5 - $\frac{p}{q}$

• LHS ≠ RHS

:. Our assumption is wrong

so,

(5 - √2) is a irrational .
