Solution
Expression : $$\sqrt{(1057 - \sqrt{(1109 - \sqrt{(450 - \sqrt{2500})})})}$$
= $$\sqrt{(1057 - \sqrt{(1109 - \sqrt{(450 - 50)})})}$$
= $$\sqrt{(1057 - \sqrt{(1109 - \sqrt{400})})}$$
= $$\sqrt{(1057 - \sqrt{(1109 - 20)})}$$
= $$\sqrt{(1057 - \sqrt{(1089})}$$
= $$\sqrt{1057 - 33}=\sqrt{1024}=32$$
