Question

I'm reading my lesson over because I forgot how to go about some stuff and I come across this, is this technically considered wrong?

Answer 1

Technically 0 squared is 0, a square root cannot be 0. It's any whole number. 1,7,9 etc. Even though they might be irrational.

Answer 2

0 is an integer.

0^2 = 0 and the square root of zero is zero.

Answer 3

Yeah, but a square root cannot be 0, its any positive number.

Answer 4

The square root of zero is zero, so... why^^?

Answer 5

0 is not a positive number, its in between negative and positive, neutral.

Answer 6

Why does a square root have to be a positive number, as opposed to a positive number or zero?

Answer 7

Because a square root cannot be negative. I don't consider 0 to be positive. It's an integer, yes, 0^2 = 0 and the sqrt of 0 is 0 but idk :l

Answer 8

0 isn't negative. A square root can be positive, or zero. I don't see an issue at all.

Answer 9

I don't know how 0 can be a square root lol, but I'll leave it at that.

Thanks for answering my doubt (:

Answer 10

I don't know how it CAN'T be.

0*0 = 0

Sqrt(0) = 0

Answer 11

Unless you're talking about the limit as x approaches zero, since you can only approach from the right, not the left... i don't see the problem.

Answer 12
