@MarkTinsley01 No. That’s wrong. Mathematically it makes a huge difference between sqrt(16) which is only 4 (not -4) and the equation x^2=16 which is x=4 and x=-4.
The sqrt is defined as the positive solution only. It is a definition. So -4 is NOT a solution for sqrt(16)!
@AlexMonclus@MarkTinsley01@elizay560 Nope. Just get a math book my friend. The sqrt is always positive. You don’t have an equation here like x^2=4 where x is 2 or -2. The sqrt(4) is always positive and here =2.
For the term above you have only 3 as solution.
Btw: Studied math dude here 😋
