Depends on who you ask.
It's a matter of convention, similar to
0^0 = 1.

Hi, Hope I can help,
.
Does the square root of 0 equal undefined, no solution, or 0
.
Here are some more examples
.
+sq+rt%2825%29+=+5+ or (-5) ( +5%5E2+=+25, or +5%285%29=25+, +-5%5E2=25+, or +-5%28-5%29=25+ )
.
+sqrt%289%29+=+3+ or (-3) ( +3%5E2=9+, or +3%283%29=9+, +-3%5E2+=9, or +-3%28-3%29=9+ )
.
The square root of a number is multiplied by itself to get the number inside the square root
.
So for +sqrt%280%29+, what number multiplied by itself will equal "0"?
.
The answer is "+0" or "-0", or just "0"
.
( +0%5E2+=+0+, or +0%280%29+=+0+ )
.
It is not undefined, because it does exist, and no solution is the same as undefined
.
So your answer is +0+
.
Hope I helped, Levi
