Answer 1

To combine the radicals \(28\sqrt{} + 38\sqrt{}\), we need to simplify them by factoring out any common terms.

However, it seems that the radicals are incomplete as stated, possibly due to formatting issues. Let's assume the radicals are \(28\sqrt{a} + 38\sqrt{a}\), where \(a\) is a variable. In that case, you can combine them as follows:

\[ 28\sqrt{a} + 38\sqrt{a} = (28 + 38)\sqrt{a} = 66\sqrt{a} \]

If the radicals are different (for example, \(28\sqrt{2} + 38\sqrt{3}\)), they cannot be combined further since they are unlike terms.

Please confirm the radicals involved or specify them, and I'll provide the correct addition or subtraction.
