Example of Simplifying 36\sqrt{36}, 169\sqrt{169}, and 225-\sqrt{225}

To evaluate these expressions, determine the principal square root for each and apply any external negative signs. For 36\sqrt{36}, the principal square root is 66 because 62=366^2 = 36. For 169\sqrt{169}, the positive square root is 1313 since 132=16913^2 = 169. For 225-\sqrt{225}, first find the principal square root of 225225, which is 1515 (as 152=22515^2 = 225), and subsequently apply the trailing negative sign located in front of the radical to attain 15-15.
