Square roots can be negative, but when talking about the square root it's normally assumed to be the principal square root, which is the positive one. permalink fedilink source parent [–] mexicancartel@lemmy.dbzer0.com 1 point 2 years ago* Nope. To clarify, square roots are the opposite of squaring. Now ask yourself: What is 10² ? What is (-10)² ? If you get the same answer, then they are both the roots of the answer. +10 and -10 then gets together called ±10 permalink fedilink source parent
