Q3

Fill in the blanks to complete the proof of

2 - \sqrt{5}

as an irrational number, provided

\sqrt{3}

is an irrational number.

Let’s assume

2 - \sqrt{5}

be a rational number

\Rightarrow 2 - \sqrt{5} = \frac{a}{b}, b \neq 0

\Rightarrow \sqrt{5} =

(i)___________ which is a (ii)_________ number.

\Rightarrow \sqrt{5}

is a rational number.
But

\sqrt{5}

is an irrational number.
Hence, we have arrived at a contradiction.

∵ 2 - \sqrt{5}

is an irrational number.
