What is not a real number?

Imaginary numbers are numbers that cannot be quantified, like the square root of -1. The number, denoted as i, can be used for equations and formulas, but is not a real number that can be used in basic arithmetic. You cannot add or subject imaginary numbers. Another example of an imaginary number is infinity.

Is Root 0 defined?

the square root of 0 is defined – in fact, it is 0. 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 ).

Does a square root have 2 answers?

There is no equation to solve, thus there are no solutions to speak of. Square root of positive real numbers are defined to take the positive root. It is from definition but not from calculation. x 2 =49 does have 2 roots, but we will only take the positive one for square root.
