+5265 Thank you, melody! So, the square root of 25 can be ±5 because 5*5=25 and (-5)*(-5)=25.
HOWEVER, (-5)*5 is NOT 25, it is -25.
+8262 The answer can be either:
\(\sqrt{25}=5\)
Or
\(\sqrt{25}=-5\)
If you get the square of both numbers, they both equal 25:
\(-5^2=5^2\Rightarrow 25=25\)
Multiplying two negatives equals a positive result.
Hope it helped!
+118687 Rarinstraw, I think that you should expand on your answer.
The poster is probably wondering why -5 isn't an answer too :/
