They are inverse relations. That is,if A and B are any numbers andif A is the square of Bthen B and -B are the square roots of A.
They are called real numbers. Negative square roots must be complex numbers.
No. The square roots of perfect squares are rational.
There are no real square roots of -256. But using complex numbers the square roots of -256 are 16i and -16i.
There are no following numbers!
The square root of every perfect square is an integer. However, there are also square roots of numbers that are not perfect squares.
I posted an answer about cube roots of complex numbers. The same info can be applied to square roots. (see related links)
No. The square roots 8 are irrational, as are the square roots of most even numbers.
They are inverse relations. That is,if A and B are any numbers andif A is the square of Bthen B and -B are the square roots of A.
Numbers with square roots that are whole numbers
They are called real numbers. Negative square roots must be complex numbers.
No. Lots of square roots are not rational. Only the square roots of perfect square numbers are rational. So for example, the square root of 2 is not rational and the square root of 4 is rational.
No. The square roots of perfect squares are rational.
There are no real square roots of -256. But using complex numbers the square roots of -256 are 16i and -16i.
Negative numbers have no real square roots. In terms of complex numbers, the square roots of 43 are +j6.5574 (rounded) and -j6.5574 (rounded)

Square roots of negative numbers ARE possible. I guess you haven't been introduced to "imaginary numbers" and the letter "i".
