To simplify this expression, we can first simplify each square root:
√3 √20 = √(320) = √60
√19 √20 = √(1920) = √380
√19 √127 = √(19127) = √2413
Now we can substitute these simplified values back into the original expression:
√60 - √380 + √2413
Since none of these square roots can be simplified further, this is the simplified form of the expression.
