Yes. It is possible when either a or b equals zero. Since √0 = 0, adding zero to a radical or to its radicand does not change the value.

23

Which of the following did you include in your response?

A
Yes, it is possible to have the sum of square roots equal the square root of the sum of the radicands.
B
If either a or b equals zero, then the sums would be the same.
C
Since the square root of 0 is 0, adding it to a given radical would not change the radical. Also, adding zero to the radicand would not change its value.
