Answer:

5

Step-by-step explanation:

You need to start from the inner root ie \sqrt{225} =15

So that would simply it to,

                                     \sqrt{21+15}  =\sqrt{36}

Again simplifying,

                                     \sqrt{19+6}=\sqrt{25}

                                                  =5
