This question has actually probably been asked to fatality already, however I’m a newcomer to this subbsci-ch.org and just wanted to acquire this question off of my chest (it’s been bugging me because that the past few hours). I’m around to it is in a small in high school, and so far, root (specifically, a square root) have actually been characterized to me together a number that, when multiplied by itself, returns a value equal come the multiple squared (I just realized that this definition is yes, really repetitive, but...it’s the best I can do in a few seconds.)

Knowing this, what is the square source of zero? Is zero time itself zero? exactly how do exponents work with zero?

This is really around fifteen questions wrapped right into one, yet I kinda acquired derailed after i began.

You are watching: What is square root of 0

Yeah, it's just 0. 0x is identified for any kind of strictly hopeful x, and they're every 0. In various other words, 02 = 0, 03 = 0, 0114.4289 = 0.

It goes wrong when the exponent is 0 itself or negative, therefore 00 and 0-1, 0-2.458 and so on are all undefined.

Ah, and also that’s due to the fact that of how negative exponents do the number a portion with the base together the denominator, right? and also of course, dividing by zero is a cardinal sin.

But what around the zero exponent? that makes whatever 1, doesn’t it? Or is that simply my incomplete, sophomore-level understanding?

But prior to all that, many thanks for the help. This question has actually been bugging me because that a while, prefer I said.

Yes, the square source of zero is zero.

(This is past high-school-level math, however it's feasible to prolong the real numbers by adding an extra number which squares come zero however isn't zero itself—this gives rise come the twin numbers, which have some exciting properties.)

Dual number

In linear algebra, the double numbers prolong the genuine numbers by adjoining one new element ε v the residential or commercial property ε2 = 0 (ε is nilpotent). The arsenal of twin numbers creates a certain two-dimensional commutative unital associative algebra end the real numbers. Every dual number has the type z = a + bε whereby a and b room uniquely determined real numbers. The twin numbers can likewise be believed of as the exterior algebra that a one-dimensional vector space; the general situation of n dimensions leads to the Grassmann numbers.

Unfortunately, mine feeble high-school mind fails to completely comprehend this, but it’s a cool check out anyhow. I don’t really like how we seem come be taught a rule, told that the preeminence is absolute, then basically being called “except for that instance.”

The means we teach math simply irks me in general, but this is among the biggest cases. Thanks for the response.

Wouldn't such equipment break an easy algebra?

02 is 0, and also ε2 is likewise 0. Thus ε2 = 0 = 02 , ε2 = 02

otherwise 02 != 0, then we'd have actually a problem where 0some big number =! 0.
