Answer 2

Answer:

2

Step-by-step explanation:

Given: a=64 ; b=289

We know, $\sqrt{64}=8$ and $\sqrt{289} =17$

$\sqrt{\sqrt{a}+\sqrt{b} } - \sqrt{\sqrt{b}-\sqrt{a} }$

= $\sqrt{\sqrt{64}+\sqrt{289} } - \sqrt{\sqrt{289}-\sqrt{64} }$

= $\sqrt{8+17}-\sqrt{17-8}$

= $\sqrt{25} - \sqrt{9}$

= 5 - 3
