neonofarm [45]

Answer:

B.  √5

Step-by-step explanation:

Given:

K=\sqrt{9-4\sqrt{5}}

<h2>\implies K+2=\sqrt{9-4\sqrt{5}}+2</h2>

Rewrite 9 as 5 + 4:

= \sqrt{5-4\sqrt{5}+4}+2

Rewrite 5 as (√5)², 4 as 2² and 4√5 as 2 · 2√5:

= \sqrt{(\sqrt{5})^2-2 \cdot 2\sqrt{5}+2^2}+2

Apply the perfect square formula  a^2-2ab+b^2=(a-b)^2:

=\sqrt{(\sqrt{5}-2)^2}+2

Apply radical rule  \sqrt{a^2}=a

=\sqrt{5}-2+2

Simplify:

=\sqrt{5}
