-sqrt%28-25%29
First we factor the radicand (the -25):
-sqrt%2825%2A%28-1%29%29
The we'll use a property of radicals: sqrt%28a%2Ab%29+=+sqrt%28a%29%2Asqrt%28b%29 to separate the factors into their own square roots:
-%28sqrt%2825%29%2Asqrt%28%28-1%29%29%29
Since sqrt%2825%29+=+5 and sqrt%28-1%29+=+i:
-%285%2Ai%29
or -5i
