What is the difference between a subscript and a superscript?

Can 0 be squared?

Zero has one square root which is 0. ... √0=0. Negative numbers don't have real square roots since a square is either positive or 0.

Is Square Root of 0 defined?

the square root of 0 is defined - in fact, it is 0. This makes sense since , so naturally . Your formula, however, does not hold for all n as you claim it does - it only works for n > 0 (because the principle square root isn't defined for negative numbers, and you can't divide by 0).

Why is negative 1 squared negative?

The calculator said -1 because of the way calculators handle inputs. When a calculator sees it breaks it down in an odd way. Instead of how a person would interpret it, as squaring negative one, a calculator interprets it as taking 1 squared and returning its negative.

Is squared negative or positive?

"This is because to square a number just means to multiply it by itself. For example, (−2) squared is (−2)(−2)=4. Note that this is positive because when you multiply two negative numbers you get a positive result." - This, of course, is the exact opposite of what was asked, but it's the given response.

What is the square of negative 1?

Unit Imaginary Number The square root of minus one √(−1) is the "unit" Imaginary Number, the equivalent of 1 for Real Numbers. In mathematics the symbol for √(−1) is i for imaginary.

Why is a negative times a negative a positive?

When you multiply a negative by a negative you get a positive, because the two negative signs are cancelled out.

What does a positive and a negative equal?

Multiplying and Dividing with Positive and Negative Numbers. ... When the signs of the two numbers are the same, the answer will be positive. When the signs of the two numbers are different, the answer will be negative.

When you divide by a negative does the sign change?

The Exception: Negative Numbers There is one very important exception to the rule that multiplying or dividing an inequality is the same as multiplying or dividing an equation. Whenever you multiply or divide an inequality by a negative number, you must flip the inequality sign.

What is negative plus negative?

While it's true that a negative times a negative is a positive, a negative plus a negative is actually a negative. When adding signed numbers, it is useful to think of positive numbers as gains and negative numbers as losses. A loss plus a loss is a bigger loss.
