(-5√3)² = 25*3 = 75
√4 = 2
21/25 = 0.84
√5 = √(25/5) = 5/√5 = 5/5 = 1
1/16 = 0.0625
(0.2√10)² = 0.04*10 = 0.4
Now, plug in the values and solve:
75 + 20.841 - 0.0625 - 0.475 + 1.68 - 0.0625 - 0.475 + 1.68 - 0.0625 - 0.476.68 - 0.0625 - 0.476.6175 - 0.476.2175
Therefore, the result of the given expression is 76.2175.

76.68 - 0.0625 - 0.4
76.6175 - 0.4
76.2175
Therefore, the result of the given expression is 76.2175.
